Service details

What you're getting isn't just an API -- it's a production-ready backend.

Most developers hand you code, I hand you a system - documented, Dockerized, tested, and ready to scale from day one

This offer includes:

  1. Custom REST API design (FastAPI / Flask / Node JS / ExpressJS) 
  2. JWT Authentication & Role-Based Access Control (RBAC) 
  3. PostgreSQL or MongoDB database design with optimized indexing 
  4. Docker containerization with dev/prod parity 
  5. Full API documentation (Swagger / Postman collection) 
  6. GitHub repo with clean, commented code
I've already done this for 10+ clients across SaaS, e-commerce, and logistics -- with a 70% repeat engagement rate. 

Here's what that looked like in practice:

  • Reduced API latency by 40% under high-throughput load
  • Improved database retrieval by 35% via targeted indexing
  • Cut third-party integration timelines by 30%
Tech Stack: FastAP,I Flask, Node JS, PostgreSQL, MongoDB, Redis, Docker, JWT, REST APIs, GitHub Actions

Perfect for you if:

  •  You need a backend for your SaaS product or MVP 
  •  Your current API is slow, breaking, or unscalable 
  •  You want clean code you can actually maintain later 
  •  You're integrating third-party services (Stripe, OAuth, etc.)

Why me over others?

I've shipped across industries, I own the full lifecycle — architecture to deployment — and I communicate proactively. You won't be chasing me for updates.
Let's build something that lasts.
