NoSQL Couch & Mongo Jobs

I am already more than halfway through building a multi-tenant ERP platform offered as SaaS. The current stack is React on the front-end with a Node.js (Express) API, and subscription payments are flowing through an integrated payment-gateway module. What’s left is to finish the remaining business-logic layers, tighten up the UI, and prepare the whole product for production release. I’ll give you access to the existing Git repository, detailed module road-maps, and the payment gateway keys already in place. Your job is to pick up the codebase, complete the unfinished modules, squash any bugs you find, and push clean, well-commented commits back to the repo. Key expectations: • Keep everything in React + Node.js, following the existing component and controller patte...

A mature + React + TypeScript web-app is already 80 % complete; my next milestone is a one-month sprint (≈ 6 h/day, remote) to wrap it up, hard-test it and push a rock-solid version toward production. Videocall every day 1:1. Cibersecurity is a +. Scope of work Over this weeks the codebase needs three clear groups of improvements: • New user-facing features: registration & role-based user management, an in-app notification system and a personalised dashboard. Face Id ect • Service integrations that extend existing API routes. • UI/UX refinements with Tailwind while keeping the component library consistent. Alongside that primary goal, you will be moving through the existing repo correcting lingering bugs, checking permission flows, cleaning test data vs....

I already have an IPO tracking app in production and now need a dedicated backend service that can fetch allotment results from the 30-plus Indian registrars the moment they go live. The entire service must be written in Node.js, since the rest of my stack is JavaScript based. Core expectations • Connect to every major registrar (KFintech, Link Intime, Bigshare, Cameo, Skyline, etc.) and return real-time allotment status using the usual identifiers—PAN, application number, DP/Client ID, or combination thereof. • Normalise the various HTML, CSV, PDF, and basic API outputs into a single clean JSON response. • Build a set of REST endpoints with simple auth, comprehensive error handling, and logs I can pipe into my existing monitoring. • Provide clear deploym...

I’m building a full-featured website for our new pickleball league and need an experienced backend developer to bring the real-time pieces to life. The stack is already chosen: Node.js (Express or NestJS) with PostgreSQL as the primary database. Core tasks • Live player auctions – real-time bidding, instant bid notifications, and a full auction history log powered by Socket.IO. • Live match scoring – endpoints that push each team’s score and stats seconds after every rally so the front-end can update instantly. • Secure auth – JWT sessions plus OTP or token-based magic-link login for captains, admins, and bidders. • Media handling – upload player photos and team assets straight to AWS S3 (or Cloudinary if you prefer) and stor...

I need like Coach Surfing web + mobile app. I have an existing Flutter mobile application that already communicates with a Node.js backend. I now want to push it further: tidy up the current codebase, add several new screens, tighten the API layer on the server, and introduce a small yet meaningful AI feature (think personalised recommendations or basic natural-language queries—exact scope to be agreed together). Here is what I need from you: • Flutter work – polish the present UI, wire in the new screens I will supply as Figma frames, and be sure state management stays clean and predictable. • Node.js work – extend the current Express API, connect the new endpoints to MongoDB, and add role-based authentication so the app can distinguish between guest and...

I need a skilled backend developer to build and deploy a secure user-authentication and management service written in Node.js and hosted on Google Cloud Platform. The project is green-field, so you’ll be setting up everything from the ground up: server environment, database connection, and the authentication flow itself. What I expect • A clean, well-structured Node.js codebase that exposes REST (or GraphQL, if you prefer) endpoints for sign-up, login, password reset, refresh tokens and role-based access. • Deployment to GCP using the service you judge best (Cloud Run, App Engine, GKE, etc.) with environment variables managed safely and logs viewable in Cloud Logging. • A small, automated CI/CD pipeline so updates go live with minimal downtime. • Clear, d...

I’m kicking off a full-stack project and need an experienced developer who can attack both the front-end and back-end at the same time. The stack is already defined: Node.js (my preferred choice even on the front end), React.js with Redux, and a microservice layer in Java Spring Boot. RESTful APIs, PostgreSQL or MySQL on the relational side, and MongoDB for document storage are all part of the architecture. Speed matters—I’m looking to see working code as soon as possible, so we’ll iterate quickly and ship incremental features rather than wait for a big-bang release. Modern JavaScript (ES6+), async/await patterns, and clean module structure are must-haves; so is writing well-tested, production-ready Java Spring Boot microservices. High-level deliverables: • R...

I need access to battle-tested enterprise repositories that exceed 50,000 lines of code. The primary goal is to run AI benchmarking, perform deep architecture reviews, and carry out engineering evaluations for technical due-diligence work. Real-world complexity is essential—simple CRUD samples will be declined. Preferred technology foundations include Java, .NET, Python, Node.js, or React, ideally containerised with Docker or orchestrated through Kubernetes and deployed on AWS, Azure, or GCP. Repos hosted on GitHub, GitLab, Bitbucket, or a private Git server are all welcome. Any supplementary assets—such as PRD/BRD documents, Jira tickets, detailed API docs, architecture diagrams, deployment playbooks, or test artefacts—will significantly strengthen your submission and ...

Cloud360 is moving into Phase 2, a cycle dedicated solely to squashing the bugs that surfaced after launch. I’ll hand you a clearly documented backlog—steps to reproduce, log excerpts, and a link to the Git repository—and expect clean, well-commented patches submitted via pull request. Each fix must be accompanied by unit tests and must pass the existing CI pipeline before we promote it to our staging environment. The stack is a typical cloud-native mix of Node.js, React, PostgreSQL, Docker, and AWS services, with automated testing through Jest/Mocha and a CI/CD workflow. If you are comfortable diagnosing issues in this ecosystem and can work iteratively while keeping an eye on regression risk, you’ll fit right in. Deliverables • Patched source code for eac...
