About this gig
Are you looking for a professional Backend Developer to build a secure, high-performance, and scalable REST API for your web or mobile application?
You have come to the right place!
I specialize in building production-grade backend systems using Node.js, Express, Fastify, TypeScript, PostgreSQL, Prisma, and Redis. I follow clean 3-Tier Layered Architecture (Controller -> Service -> Repository) to ensure your backend is easily testable, modular, and built to handle thousands of concurrent requests.
WHAT I OFFER:
Scalable RESTful API Design (Clean endpoints, proper HTTP status codes & REST conventions)
Strict Runtime Validation using Zod DTOs (Zero invalid payloads entering your DB)
Centralized Error Handling (AppError hierarchy with safe error responses)
Robust Database Modeling: PostgreSQL / MySQL with Prisma & Drizzle ORM
Database Optimization: ACID transactions, Row-locking (Race condition prevention), and Indexing
Secure Authentication: JWT Access & Refresh Token rotation, HttpOnly cookies, RBAC authorization
High Performance & Caching: Redis Cache-Aside pattern, Sliding-Window Rate Limiting
Asynchronous Job Queues: BullMQ + Redis for background tasks & emails

FAQ
How do you organize the backend codebase?
I follow professional 3-Tier Layered Architecture (Controllers for HTTP, Services for business logic, and Repositories for data access). This keeps the code modular, scalable, and easy to maintain.
How do you prevent database bottlenecks and race conditions?
I design normalized schemas with B-Tree/GIN indexing, avoid N+1 query problems using eager loading/joins, and handle concurrent operations using atomic ACID transactions and row locking (SELECT ... FOR UPDATE).
Can you integrate third-party APIs like Stripe or AWS S3?
Yes! I can implement secure Stripe checkout with HMAC signature-verified webhooks, and AWS S3/Cloudflare R2 direct file uploads using secure presigned URLs.
Will the API be containerized with Docker?
Yes, I can provide a multi-stage production Dockerfile and a docker-compose.yml file with Node.js, PostgreSQL, and Redis ready to run in any cloud environment.
