Node.js Jobs

I need a reliable system that can take our prepared text and video assets and publish them automatically across multiple social networks. After our kickoff call I will share the exact platform list and credentials, but the solution should be flexible enough to add or remove channels without major re-work. Key objectives: • Configure multi-platform auto-upload through Comet, mapping captions, thumbnails, tags, and any platform-specific metadata. • Create scheduling rules so each post goes live at the time I set—daily, weekly, or according to custom calendars. • Build a distribution workflow that queues content, validates it against each API’s limits, and triggers retries on transient errors. • Add an error-detection layer with clear logging and alerts ...

I need a strong developer who can debug TypeScript code with ease and assist with deep debugging and troubleshooting of my current script, including root-cause analysis, refactoring fragile logic, and improving overall maintainability.

I’m building a school project and need a web-based AI bot that can act like a friendly, knowledgeable tutor. Once deployed online, the bot should: • Answer student questions in plain language • Walk through homework problems step by step • Suggest personalised study tips and resources I don’t mind whether you use Python (Flask / FastAPI), Node.js, or another sensible stack, as long as the final product runs smoothly in a browser without extra paid services. Feel free to tap into OpenAI, Hugging Face, or similar APIs if that speeds things up. Deliverables I need from you 1. Full source code, clearly commented. 2. A lightweight web UI where students type or upload a question and get an immediate response. 3. A short README with setup instructions so I ...

I’m working with the AI-Powered Physiotherapy Recovery Flutter template from CodeCanyon (see link above) and now need a purpose-built backend to handle its scheduling flow. The mobile side is ready; what I’m missing is the server logic that lets therapists create, update, and cancel treatment sessions while automatically sending SMS reminders to patients ahead of each appointment. My priorities are clear: – Robust session scheduling and management endpoints that the existing Flutter code can call seamlessly (REST or GraphQL, your choice as long as it’s well-documented). – A background job or queue that fires SMS reminders at configurable intervals—Twilio, Nexmo, or another SMS gateway works for me provided it’s abstracted cleanly so I can swap p...

I need a single developer who can take my company’s custom web-app idea from blank screen to production-ready release. The frontend must be responsive and polished; React or Vue are both fine, provided the choice supports fast performance and clean component structure. On the server side I’m flexible—Node.js, PHP, or Python all work as long as the stack you pick is the best fit for the project and integrates smoothly with the database and any external APIs we decide to pull in. You’ll be responsible for wiring the whole flow: interface, business logic, data layer, and deployment guide. I value clear, proactive communication and short feedback cycles, so expect quick turn-around replies from me and please reciprocate with frequent progress updates or demo links. De...

I run a React + Node.js web application backed by PostgreSQL and Prisma, and I’m looking for a junior full-stack developer who is comfortable working in Arabic to help me ship a series of small but important enhancements. (Put your price for: Duration: 15 Hours in one week) The immediate priorities are: • Building an interactive dashboard that consumes our existing REST endpoints and presents data in a clean, responsive layout. • Refining the overall user experience—tidying up flows, polishing micro-interactions, and ensuring consistent design language. • Extending both the frontend and backend as needed: new UI components in React, new routes/controllers in Node.js, and the corresponding Prisma queries for PostgreSQL. On the frontend you’ll mostly ...

I need an embeddable chat box that sits on my website and allows a private, two-person conversation between me (manager) and a customer. No sign-up, password, or account creation should get in the way—when a customer clicks the chat icon or a direct link I email them, the window simply opens and we can start talking. Core objectives • Web-only integration (the platform choice I selected) • One manager seat, one customer seat per session • Real-time text exchange with automatic refresh or websockets so neither side has to reload the page • Clean code I can drop into any page plus a brief setup note (where to paste the script, how to start a new session) Optional niceties—if you already have them in your toolkit, feel free to include typing indicator...

I’m putting together a proof-of-concept and need a single-page web app, built in React, that mimics the look and feel of Dexscreener but runs entirely on simulated data. Candlestick charts must be rendered with , while the surrounding stats—price, 24 h change, market cap, volume, etc.—update in real time. Flow I envision • A Telegram bot (already under my control) sends JSON payloads with the latest price, market cap and any extra metrics I decide to test. • A lightweight server receives those webhook calls and streams the data to the front-end (WebSocket or SSE—whichever you find cleaner). • The React UI redraws the active candle and refreshes all displayed figures instantly, giving the impression of a live market feed. Key requirements &...

Role: AI WhatsApp Chatbot Developer We are building an AI-powered WhatsApp Sales Agent for a Japanese Car Dealership. Goal is to create a Gemini-style AI chat experience inside WhatsApp that allows users to search vehicles naturally using AI instead of buttons or fixed menus.

I want the running total revenue from my Shopify store to show on a Wi-Fi-enabled physical counter that sits on my desk. The job is to build the small bridge between Shopify’s JSON API and the hardware. Here’s what I already have and what I need from you: • Data source – Shopify: I only care about the store’s Total revenue figure. A lightweight call to the REST Admin API (or GraphQL if you prefer) is enough. I will supply the private-app credentials. • Destination – Hardware counter: It connects over Wi-Fi. You can target it with plain HTTP, WebSocket, or MQTT; whichever is simplest to flash onto a common ESP8266/ESP32 controller. I can handle the flashing if you give me the compiled binary or the Arduino/PlatformIO project. • Service layer:...

I have a working file-transfer script that already handles all the send/receive logic; now I need it wrapped into a polished desktop application that installs cleanly on Windows, Linux and macOS. After installation, the embedded sync-engine must run automatically at regular, short intervals—every few minutes—without user intervention, quietly polling our remote server and pushing or pulling any file changes it detects. What I still need built is the installable package itself along with a lightweight settings interface that supports both light and dark themes. The GUI only has to let users confirm the target folder and, if they wish, pause or resume syncing, so the design can stay minimal yet visually impressive. Under the hood the sync routine should launch on startup (servic...

I need a cloud-based Payment collection app that lets my staff and customers settle invoices through UPI AND CASH while also giving us the option to record UPI, Cash, Cheque receipts in one place. Think of it as a lightweight, multi-tenant service we can log into from any browser or phone, issue a payment link or on-screen QR, mark physical cash or cheque as “received”, and instantly see it reflected in a consolidated dashboard. Core flow • A customer or field agent chooses UPI, Cash, or Cheque. • For UPI we present a dynamic QR or intent link and verify the callback. • Cash and cheque entries let the user capture amount, payer, reference photo, and status (for cheques: pending, cleared, bounced). • Every transaction updates real-time reports, sends...

We need a Node.js Expert from Pakistan or India we need work for Guidance and Help we need work for long term

I need hands-on assistance, at my Bengaluru office, to keep a live .NET 6 back end and Angular 12 front end running smoothly. The immediate focus is two-fold: • Systematic bug fixing—tracing issues in the Web API, Angular components, and integration layers, then committing clean, tested patches. • Regular code reviews—walking through pull requests with me, flagging design or performance concerns, and suggesting improvements that align with current best practices. Expect to work directly on the existing Git branch structure (Visual Studio / VS Code, Git, and typical dev-ops tools are already in place). Face-to-face collaboration during standard weekday hours is essential; remote work is not an option for this engagement. Deliverables will be accepted once each id...

I have an informational web application to be built and prefer to work with freelancers who are already based in Bengaluru so we can easily align on occasional in-person discussions and faster iterations. The project centres on a clean, responsive site that presents curated content rather than e-commerce or social networking features. Core requirements include: • Front-end: modern, component-based framework (React, Vue or similar) with SSR or strong SEO support. • Back-end: lightweight REST or GraphQL service, preferably in Node.js or Python, with clear separation of concerns and straightforward deployment to a standard cloud stack (AWS, GCP or Azure—whichever you are most comfortable with). • CMS or admin interface that lets non-technical staff update text, imag...

The core of my project is an API service already running on .NET 5 and paired with an Angular front-end. I need hands-on, task-based support to keep new features moving quickly while maintaining clean, testable code. Here’s the current stack and workflow so you know what you’ll be jumping into: • Backend: ASP.NET Core 5, Entity Framework Core, RESTful endpoints. • Front-end: Angular (latest stable), RxJS, Material. • DevOps: Git, pull-request reviews, CI builds on GitHub Actions. Typical tasks you could pick up include: • Expanding endpoints and DTOs. • Wiring new Angular components to the fresh endpoints. • Adding unit / integration tests where coverage is thin. • Fine-tuning performance or refactoring when technical debt appe...

Right now every allocation, reconciliation, and customer report is driven out of a collection of Excel spreadsheets. I want a single web-based platform that ingests the daily QCA schedule file the moment it lands, matches each customer name to our master list, and then—using the latest SLDC meter data—calculates the exact pro-rata energy actually delivered to more than thirty customers spread across five plants. The application must: • Parse the raw Excel schedule automatically, validate that the plant totals equal scheduled generation, and raise an instant alert (email, pop-up, or SMS—your call) whenever there is any mismatch. • Feed those validated numbers into a live dashboard so the team can see, in real-time, how each plant’s allocation is trackin...

I need a single WebExtension that runs in both Chrome and Firefox and turns our current manual workflow into a one-click process. Its core job is data collection—capturing information from pages we specify—while also handling the little chores my team repeats every day: filling forms, scraping targeted fields, and kicking off routine browser actions such as page refreshes or button clicks once certain conditions are met. The add-on must connect cleanly to three parts of our internal stack: • our CRM system (REST APIs already documented) • the project-management tool we use (webhook support available) • a central database for long-term storage (PostgreSQL) Please build with the standard WebExtension/Manifest V3 approach so we can maintain a single code...

I have an existing web application built using React.js (frontend), Node.js (backend), and PostgreSQL (database), and I am looking for a highly experienced expert who can both thoroughly manually test and actively fix/repair the entire application end-to-end. This is not a testing-only role—the developer must identify and correct all issues in the codebase (frontend and backend). The scope includes detailed manual testing of all modules, user flows, validations, APIs, and edge cases; fixing all discovered bugs and errors; resolving console, runtime, and server-side issues; improving UI/UX where required; and making the complete UI fully responsive across mobile, tablet, and desktop devices using modern responsive design practices. The work must result in a stable, production-ready ap...

Our Strapi-based CMS backend (with APIs) is live but facing major APIs issues (e.g., errors, performance, routing). Need an expert for immediate support, debugging, and fixes.

Key Requirements: - 4+ years with Strapi (v3/v4/v5) and Node.js/Nest.js. - Proven track record fixing Strapi Node API problems: APIs sync with latest version, 404s on routes, permissions/drafts misconfigs, middleware async issues, N+1 queries. - Deep knowledge of Strapi controllers, services, lifecycles, custom plugins, and error handling. - Database optimization (PostgreSQL/MongoDB), caching (ISR, Redis), and deployment (Docker/AWS). - Git proficiency; React frontend integration experience a plus (our stack). - Ability to r...

I need a full WhatsApp Business API workflow built for our coaching institute’s existing WhatsApp number. The goal is to handle common student queries instantly, guide them through tap-friendly menus, and feed every interaction into a live-updating Google Sheet that my team can monitor in real time. Core flow • When a prospect messages “Hi”, an automated greeting should fire and present three interactive buttons: Course Offerings, Admission Process, and Contact Support. • Tapping Course Offerings or Admission Process must trigger rich, structured replies with detailed course information; Contact Support should collect their name, phone, and the topic they wish to discuss, then forward it to a human agent. • All captured data—timestamp, phone ...

I’m in the middle of a CROMA overhaul and the single, driving objective is to refresh existing features by squeezing every last millisecond out of them. No new bells and whistles—just a focused performance pass aimed at raw speed. Here’s the picture: React on the client side, Node.js/Express talking to a MongoDB cluster, all containerized in Docker and running on AWS ECS. I already have baseline profiling data and a staging environment waiting; once we start, you’ll get full access so you can re-profile, isolate the slow spots, and rewrite or refactor whatever is holding us back. Deliverables • A set of well-commented code changes or configuration tweaks • A before-and-after benchmark report (same test suite, same hardware) showing at least a 35 % dr...

I’m ready to take from a simple landing page to a fully-functional live baseball experience where visitors can watch the action and wager on the very next pitch. Core build • Real-time betting interface – odds and bet slips must update in milliseconds so users can lock in a wager before the pitcher winds up. • “Game Guru” admin console – a single operator should be able to appear on screen with Video commentary, speak over the stream in true live-TV style, and moderate chat or abusive behavior on the fly. Technical notes I’m flexible on stack, but latency is critical. WebSockets (Node.js, Phoenix, or similar), a modern front-end framework such as React/Vue, and secure payment APIs are the baseline I’m expecting. Integrate wha...

ooking for a Developer to Build a Custom UPI-Based Earning App + Admin Panel I want to build a fully working earning app like: Reference Apps: - 789Pay → [login to view URL] - HKPay - IncoinPay - LakshmiPay This is not a basic earning app — it must work like a self-controlled UPI-based gateway for deposits and withdrawals between users, just like the apps above. Core App Features: - UPI Deposit using apps like PhonePe, Paytm, Freecharge, Mobikwik, Slice, etc. - Auto Transaction Tracking (no Razorpay or payment gateway — via app scraping or any method) - Custom Wallet: Deposit, Withdrawal, Balance - Order Auto-Matching System: One user’s withdrawal = another’s deposit - Referral Commission (1.5% to direct, 0.3% to indirect) - Admin Manual Control Option - W...

This is PHASE 2 of an already existing project. I need a full-stack Flutter application that runs smoothly on iOS, Android, and the web, allowing landlords in Cameroon (and ultimately all of Africa) to publish room listings while tenants browse, filter, and book viewings. Every booking fee will be held in an escrow wallet until the viewing is completed, so the payment flow has to be airtight and auditable.

I am looking to build a custom SaaS web application that works smoothly on desktop and Android devices (mobile browsers). The website is only a functional reference for user flow and features. Design, code, branding, and content must be completely original. This is NOT a clone.

I already run a live Apify actor that handles several internal automation tasks. It is stable and well-structured, but I now need to branch into brand-new automation flows focused on data collection and processing. Here is what I need from you: • Analyse the current codebase (Node.js + Apify SDK) so your additions slot in without breaking the existing automation tasks. • Design and build one or more new actors, or extend the current actor, to fetch data from targeted sources, normalise it, and store the output in a dataset or key-value store of my choice. • Keep the solution configurable through ENV variables or an input schema, so non-developers on my team can tweak URLs, pagination, scheduling, and output format. • Provide clear, inline comments and a short...

I want to get up to speed on visualising Instagram hashtag activity as an interactive 3D network that updates in real time, so I can explore how clusters of conversation form and evolve. Basic counts or static charts won’t help me—I’m after a high-level, spatial overview that reveals relationships between hashtags at a glance. Here’s what I have in mind. You share your screen (or meet in a recorded call) and walk me through a streamlined pipeline: pulling public hashtag data from Instagram’s API or another compliant endpoint, streaming it into Python or Node, then projecting it with a WebGL or scene—Unity, Blender, or similar is fine if that’s your preferred stack. The goal is clarity over polish: I want to see each step, understand the code, and...

I need a compact piece of code that can create an L1-eligible product listing on the Government e-Marketplace (GEM) portal. The sole focus is the “Product on GEM site” functionality— no user management, payment handling, or analytics at this stage. The script should: • Authenticate with my GEM account (I’ll supply sandbox credentials). • Push all mandatory product data— title, specifications, price, images— so the item appears in the catalogue and is flagged as the lowest (L1) offer when applicable. • Return the product ID or any response GEM provides that confirms the listing. Language can be Python, Node.js, or another mainstream stack if you can justify the choice. Keep the code clean, well-commented, and drop a short README...

I’m building a lean, first-release platform that matches companies that have spare warehouse space with businesses that need it. The scope is intentionally tight so we can validate the idea quickly while still delivering a usable service. Core user flow • Suppliers register and publish an offer that clearly displays storage size/type, price per unit, and availability dates. • Customers browse the catalogue and can instantly narrow results by location, price, or size. • Both parties receive email confirmations at each step (offer posted, request sent, booking status changed). Admin needs A simple dashboard is enough for now: I only have to view, activate, or suspend any user account. Everything else—adding or editing listings—will remain in the pub...

I need a macOS desktop application that automatically creates multiple-choice exams from an academic PDF using AI. I want to: • Upload PDFs and have the system analyze their content without requiring me to input a set of questions. • Choose, before each generation, how many questions the exam will have and how many answer choices each question will display. • When answering, have the application indicate whether I answered correctly or incorrectly and provide the justification, citing the exact article, section, or page of the syllabus that supports the correct answer.

I need a clean, well-structured Python module that connects directly to the Home Assistant API, handles authentication, and exposes simple functions for reading and updating entity states, firing events, and subscribing to real-time changes. Everything should be wrapped in reusable classes (ideally async-friendly) so I can drop the code into an existing project without major refactoring. While Home Assistant is the immediate focus, I also keep Google API and Gorq API integrations on the roadmap, so designing the code in a way that lets me add further REST endpoints later would be a bonus. Deliverables • Fully commented Python code (Python 3.10+) that authenticates and performs the core CRUD operations against the Home Assistant API. • A short demo script (CLI or Jupyter not...

I need a fully custom-built website that showcases a searchable, filterable product catalog. The site must be responsive, fast, and easy for me to update without relying on WordPress or Shopify. A lightweight tech stack such as HTML5, CSS3, JavaScript with a Node.js or PHP back end and a MySQL or PostgreSQL database would suit me well, but I’m happy to hear alternative suggestions that keep performance and security in mind. Core deliverables I’ll use to accept the project: • Front-end interface designed for mobile and desktop, including category navigation, product grids, detail pages, and an intuitive search/filter bar. • Back-end admin panel where I can add, edit, delete, and reorder products, upload images, and manage categories. • Basic SEO foundations (...

I am looking for a freelancer to help build a kid-focused online tutoring marketplace where parents can book vetted tutors for live online lessons. This platform will act as a marketplace, not a tutoring service itself. Tutors provide the lessons, and the platform handles discovery, booking, payments, safeguarding, and takes a percentage commission from each completed session. The platform commission will also cover operational costs such as tutor identity verification and safeguarding checks, meaning tutors are not charged any upfront verification fees.
