I’m building out a new React front-end and now need the server side to catch up. The priority is a robust Node.js backend that exposes well-structured RESTful endpoints returning clean, predictable JSON. The data layer will live in MySQL, so you’ll design the schema, set up migrations, and write queries or use an ORM—whichever keeps performance high and code readable. Although Laravel experience is welcome and I do plan to introduce a small GraphQL layer later, right now your main focus will be the REST API: authentication (token-based), role management, pagination, filtering, and solid error handling. Clear inline documentation and a concise README or Swagger / OpenAPI file should accompany each route so the React team can plug in immediately. I’m flexible...

I’m building a new service and need a backend expert who can own the entire authentication layer. The stack is TypeScript end-to-end, PostgreSQL for storage, and a React front-end that will consume your work through a clean RESTful API. Everything lives on a Linux server, so familiarity with its ecosystem is essential. Your main mission is to design and implement a rock-solid user authentication system—think sign-up, login, refresh tokens, password resets—while keeping performance tight and code readable. Alongside the coding, I need you to lock the server down: enforce SSL, fine-tune PostgreSQL roles, manage environment secrets, set up firewalls, and apply best-practice hardening so that security audits pass without a hitch. Deliverables: • Fully documented...

Shared requirements • Single-sign-on or at least a unified authentication layer across the three portals • RESTful (or GraphQL) API that cleanly separates front-end and back-end logic • Modular, well-documented code so future features slot in without rewrites • Modern stack: I’m comfortable with React + Node, Vue + Laravel, or a comparable framework—propose what you do best • Docker-based dev environment and deployment scripts for staging and production...

...FastAPI-based RESTful interface that links our internal machine-learning pipelines to several external services, making sure the data flows securely, quickly, and reliably. You will work side-by-side with data scientists and algorithm engineers; while they refine models, you will expose their work through well-structured endpoints and schedule long-running jobs with Celery. A deep understanding of asynchronous programming, background job queues, and the nuances of production-grade REST APIs is therefore essential. Key tech you should already be fluent with includes: • Python 3.x, FastAPI, Pydantic • Celery with Redis or RabbitMQ back-ends • OAuth2 / JWT for securing endpoints • Docker and Git for reproducible builds and clean collaboration Deliverab...

...Frontend Developer (React or Angular) 2–4 years experience Experience building production-grade dashboards API integration experience State management (Redux / NgRx or similar) Experience with financial or regulated products is a plus Strong understanding of UX in form-heavy flows - Backend Developer (.NET Core) Strong experience in ASP.NET Core Experience designing RESTful APIs Experience integrating third-party APIs Clean Architecture / DDD knowledge preferred Strong documentation skills (Swagger, API specs, technical docs required) Experience handling payments and secure flows is a major plus - Database Engineer (SQL Server) Strong SQL Server experience Database schema design for transactional systems Indexing, performan...

...balance updates and a full transaction history. An admin panel should allow me to view, approve, or decline deposits and withdrawal requests, manage user profiles, and monitor all gameplay rounds. Security, input validation, and clean separation between business logic and presentation are essential. Key deliverables • Fully responsive front-end (desktop & mobile). • Laravel backend with RESTful APIs, middleware-protected routes, and secure Razorpay integration. • Wallet subsystem covering deposits, balance updates, withdrawal flow, and ledger storage. • Random result engine, payout calculation, and game history per user. • Admin dashboard with user and transaction management tools. • MySQL schema, seeders, and migration files. &...

...interactive video avatars (e.g., HeyGen, Synthesia, or custom WebRTC-based avatar rendering) tied to STT/TTS pipelines. Data & File Handling: Ability to build robust data parsing pipelines for Excel/CSV files and implement automated batch processing and rollback features. API & Backend Integration: Proven ability to build middleware and integrate AI agents securely with complex ERP databases via RESTful APIs. Vision-Language Models (VLMs) or Advanced OCR: Ability to extract tabular data from PDFs using tools like LayoutLM, AWS Textract, or Azure Document Intelligence. Semantic Mapping Engine: Experience using LLMs for "Schema Matching"—the ability to find the relationship between two different data structures without manual coding. Validation & Sanitiz...
