Database Development Jobs

I need a real-time data pipeline that ingests tick-by-tick football information from the Betfair API for each match taking place in the top five European leagues (Premier League, La Liga, Serie A, Bundesliga, Ligue 1). The feed must rely exclusively on this API—no scraping—so skill with Betfair’s Streaming or Historical service is essential. The stream should enrich every tick with contextual match metadata and persist it in an easily queryable store (PostgreSQL, parquet on S3, or a solution you propose). Low-latency processing is critical; sub-second lag from the API to storage is my target. I plan to run the pipeline on AWS, so please factor in services such as Kinesis, Lambda, Fargate or similar if they fit the design. Deliverables • Codebase (Python preferred...

I have a fresh project for you — building out a CRM/business automation system for my heavy machinery rental company, Kanwarsons Infraarts Pvt Ltd (cranes, forklifts, dumpers etc. rented to govt projects and large clients like Tata, L&T, Adani). I've already put together a detailed requirements document covering: - Data model (machines, client companies, work orders, contracts, payments, sites, staff) - Payment due/overdue and contract-expiry automations - Gmail integration for work-order and reply tracking - Machine maintenance, expense, and tax/registration tracking - Machine resale valuation (cost vs revenue per machine) - HR/payroll for operators, drivers, helpers - Reports, dashboards, integrations, and a phased roadmap — please go through it before we talk. W...

I need a well-structured SQL database that turns raw sales transactions into clear insight for our monthly analytics and reporting. The core job is to design the schema, import existing sales data, and build the queries (or stored procedures) that generate our standard monthly sales report with totals, trends, and key breakdowns. Right now the data lives in CSV exports from our point-of-sale system. I want it migrated into a relational database—engine choice is open (PostgreSQL, MySQL, MS SQL, or another you recommend) as long as it handles growth and lets me run additional ad-hoc reports later. Good indexing and normalization are essential because report runs must stay quick when the dataset scales. Deliverables: • SQL scripts for creating all tables, constraints, and index...

Full-Stack SaaS Developer Needed for Multi-Tenant Digital Catalog Platform

I need a complete examination system that runs entirely over our local Windows network, so students can sit an “online” test without any internet connection. The solution must let each workstation connect to a central server, pull the exam, and push results back immediately. Key capabilities • Randomized question order so no two students see the same sequence • Per-student time tracking with an automatic lock-out when the clock hits zero • Automated grading that releases scores the moment an exam is submitted Question formats to support • Multiple choice • Short answer • Essay Administrators have to be able to build question banks, schedule exams, watch real-time progress, and export detailed results. A simple, distraction-free candi...

Certification Program Management Platform — Partially Built, Looking to Complete I am building a web platform to manage a multi-step applicant certification process from start to finish. A solid working prototype already exists and I need an experienced developer to take it to production. The workflow: Applicant receives a unique link → completes an application → acknowledges program rights and signs digitally → uploads ID documents via desktop or mobile → takes a 199-question online exam (80% to pass, with study and retry mode) → completes an in-person assessment recorded by admin → system generates all required program documents in a single applicant file. Already built (working HTML/JS prototype): Full applicant wizard with digital signature and mo...

Access-to-SQL-Server Migration — Experienced Developer Needed (Paid Assessment First) We run a business ERP built in Microsoft Access (front-end / back-end split, ~40 users). We are looking for an experienced developer to move the data (the Access back-end tables) onto Microsoft SQL Server, while keeping our Access forms as the user interface. The database is small (~300 MB of tables). This project is a short PAID ASSESSMENT — not the full migration. Before committing, we want you to review our system and tell us whether the migration is worthwhile, what it involves, and how many hours it would take. The full migration would be a separate engagement afterwards, only if we decide to proceed. Requirement — proven migration experience We will only consider developers who hav...

I need a streamlined, cloud-based inventory management system that gives me an up-to-the-second view of stock across all locations. The core of the build is real-time inventory tracking tied to automated reorder alerts so that low-stock items trigger a purchase order or notification immediately. Flexible threshold settings and simple user permission controls must be baked in from the start. A clean, browser-based interface is preferred, but I’m open to a lightweight desktop or hybrid approach if it keeps performance snappy. Although barcode scanning is not a priority for the first release, I’d like the architecture to leave room to plug that in later without a major rewrite. Deliverables • Fully functional inventory application (front end + back end) with real-time stock...

I already have five AI-generated HTML toolkit pages—one for each of my coaching services. Each page contains multiple tabs that let me move between sections and enter information during a session. What I cannot do yet is keep that information once the browser closes. Here is what I need solved: every time I finish a session I want to press “Save”, have the client’s session notes and service-specific details written to a secure database, and be able to pull that record back up the next time we meet. On the front end the tabs and existing input fields should work exactly as they do now; on the back end I need reliable storage plus a quick way to find and filter past records no matter which of the five services they came from. Deliverables • Database schem...

TITLE Full-Stack Developer – AI-Powered Career Tools Web App (Node/Postgres, OTP Auth, Admin Panel) DESCRIPTION I need a developer to build the backend, database, authentication, and admin layer for a career-tools web app. The front end (20-25 static HTML pages, fully designed) already exists and is not part of this job, it will be extended, not rebuilt. This posting covers the functional scope only; full written requirements and a private repo are shared with shortlisted candidates before final quote. THREE CORE TOOLS (all AI-powered, all require login) 1. Document Reviewer — user uploads a Document (Word .doc/.docx only), backend extracts text, sends it to an AI provider, returns a written report to the user's dashboard and by email. 2. Profile Reviewer — user u...

I’m putting together a clean, research-backed database of every licensed commercial real-estate broker active in Quebec, with a focus on South Shore, Gatineau, Montréal, and Québec City. For each broker I need: • Full name exactly as it appears on their OACIQ licence • Direct professional email address (this is the priority field) • Direct phone number • Number of sales transactions closed in the past five years—sales only, no leases • Primary geographic area or sub-market where they operate Please trace the transaction counts to publicly verifiable sources (Centris, Co-Star, brokerage press releases, etc.) so I can audit them quickly. I’m only interested in brokers who currently hold an active commercial licence; remove du...

I need a full-stack ASP.NET web application—C# on the back end, SQL Server for data—delivered in both English and Arabic with complete RTL rendering on every screen. The build is split into two clear areas: External Applicant Portal • Public registration form that captures entity details and uploads supporting documents. • Submission triggers a reference number so applicants can log in later and track real-time status updates. • All outward-facing pages must switch seamlessly between English (LTR) and Arabic (RTL) without layout shifts. Administrative Portal • Review queue showing every incoming application and its attachments. • Configurable, multi-level approve / reject workflow. Each step records the acting user, decision, and timestamp. ...

I need a focused student-management module that handles grade management end to end. The core requirement is that grades flow into the system automatically once exams are completed, so manual entry by teachers should not be part of the day-to-day workflow. The module should: • Pull exam results in real time (API, CSV import, or direct database link—whichever you propose) • Calculate final marks using configurable weightings and grading scales • Display individual and class summaries in an intuitive dashboard for teachers, students, and parents • Export reports to PDF and Excel If your solution can live inside an existing school management framework or be integrated later, even better; for now I only need the student grade component, not attendance, p...

I am building a fresh database of companies that have launched food-manufacturing operations in India during 2025–2026, with Food Processing Units taking first priority—although Atta mills, spice, rice, snacks, pickle, tea and allied segments are welcome once the core list is covered. I need every record to be clean and decision-ready: the owner or purchase-head’s name, a call-verified mobile number, factory address, and—wherever available—WhatsApp, verified email, website or social page, state and product category. Duplicates are strictly unacceptable and the phone numbers must ring through when I sample them. Please submit an Excel sheet containing 10 test leads so I can review quality, formatting and verification before we move on to the full file. On...

Tenho instalado um terminal de controlo de acessos Hikvision DS-K1T344EBFWX-E1 e preciso que cada evento gerado pelo equipamento seja gravado em tempo real numa base de dados SQL Server. O serviço ou aplicação deverá receber o evento assim que ele ocorre e inserir, de forma confiável, três campos principais: horário de entrada/saída, identificação do usuário, status do acesso (permitido ou negado)e ID do Terminal onde a picagem foi efectuada. Busco uma solução estável, capaz de se reconectar automaticamente ao dispositivo caso o link caia, e que traga logs para auditoria. A opção de desenvolver em C#/.NET usando o Hikvision SDK ou chamadas ISAPI é a que mais faz sentido no...
