RESTful Jobs

I’m planning a new web application and want one talented partner to take it from first commit to production. The stack is already set—React on the front end, Node.js (with Express or a comparable framework) driving the server side—so you should feel completely at home with modern JavaScript, component-based UI design, RESTful (or GraphQL) APIs, and the usual DevOps steps that get everything running smoothly in the cloud. The exact product domain is still flexible; what matters most is clean architecture, clear code, and a smooth hand-off. I’ll bring the product vision and designs, you’ll bring the full-stack expertise to: • set up the project structure and repository • build the React interface with reusable components and state management best p...

I have an existing backend written in .NET Core that exposes a RESTful API. I now need a hand with two things: expanding the API with a few new endpoints and squashing some stubborn bugs that are affecting current routes. The codebase sits in a private Git repository and builds cleanly with the dotnet CLI. You’ll get a detailed list of the endpoints to add or refactor, the steps that reproduce each bug, and a Postman collection for quick regression checks. Once we agree on the work, simply branch, code, test, and open a pull request. Deliverables I expect: • Updated or brand-new C# controllers, services, and any supporting classes that compile against .NET Core. • Targeted bug fixes with unit tests that prove the issue is resolved. • A brief changelog so I can re...

I need a secure, web-based panel that lets users liquidate their crypto directly into Indian Rupees. The flow is straightforward: a visitor creates an account with an email-and-password signup, checks the live conversion rate for the supported coins, chooses the amount to sell, confirms, and then reviews the completed order in a personal transaction log. Core requirements • Web interface only—no mobile client at this stage. • Real-time price feed so every quote shown and every sell order reflects the current market. • Simple user account area where people can update profile details and see an at-a-glance balance. • Transaction history page that records date, coin, INR value, status and reference ID. Technical notes You are free to pick the back-end...

I want to streamline two pillars of my customer journey through the WhatsApp Business API: end-to-end order management and secure phone verification. On the order side, the flow should cover placement, tracking, and final confirmation without requiring any manual intervention from my team. Customers need to see real-time updates, and the system must write each step back to my existing database (REST endpoint available; documentation ready). For phone verification, the system should automatically send a code, listen for the reply, validate it, and return the result to my app. No human action should be necessary once the user responds. Acceptance criteria • Single WhatsApp number handles both processes concurrently without collisions • Clear, commented code (Python, Node, or...

SENIOR SOFTWARE ENGINEER CISCO LTD July 2025 - Now Project Description: RAIDN is an enterprise-grade project portal developed for CISCO to manage, monitor, and streamline internal project workflows, data processing, and user interactions across multiple teams.

I’m building a nonprofit smart-locker network and need a developer to stand up the entire backend plus a lightweight web dashboard. The lockers will be opened only after a biometric match—ideally fingerprint or facial recognition—so the API you create must handle secure enrollment, matching, and audit logging without ever storing conventional IDs, phone numbers, or payment data. Core requirements • RESTful (or GraphQL) API hosted on AWS, with a clean data model for lockers, users, and biometric templates • Biometric logic that can accept fingerprint or facial recognition data, hash it securely, and return match / no-match results in under two seconds • Automatic locker assignment, occupancy tracking, and remote release commands, exposed through a sim...

We are looking for an experienced React.js and Node.js developer (Full Time Freelancer, not an Agency or Part Time freelancer) to develop and integrate APIs for our web application. The developer will be responsible for creating secure, scalable, and well-documented APIs and connecting them with third-party services. This project involves backend API development, third-party service integration, and frontend API consumption where required. ✅ Responsibilities: Develop REST APIs using Node.js and Integrate third-party APIs / external services Connect APIs with React.js frontend Implement authentication systems (JWT, OAuth, API Keys, etc.) Handle data validation, error handling, and performance optimization Write clean and maintainable code Provide API documentation (Postman / Swagger pref...

I’m looking for a Playwright-based framework that automatically exercises our REST and GraphQL endpoints against the staging environment. The goal is a maintainable suite that can be triggered on every build and gives us fast feedback before we promote code to production. Here’s what I need: • Comprehensive Playwright test scripts that cover core flows such as login, key form submissions, and common data-validation scenarios (I’ll provide the exact endpoints and payloads once we start). • A clear way to parameterise base URLs so I can later point the same suite at local or production environments without code changes. • HTML/JSON reports generated after each run and stored in a folder I can archive in the CI pipeline. • Step-by-step documentati...

I’m extending an in-house web application and need a React specialist who can work on-site in Hyderabad for the duration of the sprint. The core UI is already scaffolded; what’s missing is the feature layer and the API wiring. Here’s what you’ll be shaping: • Integrate RESTful APIs, GraphQL endpoints, and several third-party services directly into the React codebase, ensuring consistent error handling and state management. • Build secure user authentication flows (signup, login, token refresh) that hook cleanly into our existing backend. • Add real-time notifications—WebSocket or SSE is fine as long as latency stays low and the UI updates smoothly. • Implement reusable data-visualisation components (think charts, graphs, dashboards)...

We’re looking for a skilled full-stack developer to provide part-time, ongoing engineering support for an evolving product. The work focuses on incremental improvements rather than a one-time build, including frontend UI enhancements, admin panel updates, backend logic updates using Python, and API integrations with internal and third-party services. Experience working across both frontend and backend systems, including Python-based backends with REST/JSON APIs and relational databases (such as SQLite or PostgreSQL). On the frontend, familiarity with Svelte, TypeScript, and modern CSS frameworks like Tailwind CSS is a plus. The pay rate is open right now so please provide your proposed pay rate. As the product grows, support may scale or expand to additional resources to help acce...

I’m looking for reliable support on a part-time basis to move my product forward end-to-end. The stack is Django on the back and React on the front, so you’ll be jumping between API work, data models, and the React UI as needed. Everything you ship should be clean, well-tested, and committed through Git. What you’ll actually do • Tackle full stack development tasks: design or update Django views, models, and REST endpoints, then wire them into React components and hooks. • Squash bugs and refactor pieces of the codebase when they slow us down. • Collaborate with me over short stand-ups and async chat; push incremental PRs so reviews stay quick. Acceptance criteria • Code merges without breaking existing tests and includes new coverage where relev...

(Russian required) It doesn’t have to be an automatic or cloud-based integration. A manual approach is also possible, by exporting data from syrve and importing it into Minimax. There will be no reverse data flow — the integration will be one-way only. I need a working bridge between Syrve Office 2025 and the Serbian cloud accounting platform Minimax, equivalent to the ready-made 1С connector widely used in Russia. The goal is for my restaurant back-office to push and pull data automatically, sparing my team from duplicate entry and giving our accountant clean, real-time numbers inside Minimax. Scope of synchronisation • Inventory lists must stay identical in both systems so stock movements registered in Syrve appear in Minimax without manual uploads. • Financial...
