About this gig

Clean, production ready REST APIs built with Node.js or FastAPI.

I build backend systems that are fast, secure, and easy to maintain, not just endpoints that technically work, but APIs structured the way a real production app needs.


Some of what I've built:

  • A REST API with JWT authentication, role based access control (RBAC), file upload, and rate limiting, fully documented with Swagger UI
  • Backend systems powering a university platform handling admissions and payment processing for hundreds of users
  • Database driven APIs using PostgreSQL, MySQL, MongoDB, and Supabase


What you get:

  1. Clean, well structured, documented code
  2. Secure authentication and authorization when needed
  3. Database integration (SQL or NoSQL, your choice)
  4. Clear API documentation (Swagger/OpenAPI)
  5. Code that's easy for your team to extend later


Why work with me:

I don't just write code that passes a test, I build backend systems that hold up under real traffic and real users. Every API is built with proper error handling, validation, and security in mind from day one.


Tell me what your API needs to do and I'll come back with a clear scope and timeline.

I'm a full stack developer based in Lagos, Nigeria, building fast, production ready websites, web apps, and backend systems. Since 2024 I've shipped real platforms, university admissions and payment processing, AI powered content pipelines, secure REST APIs with authentication, and e-commerce systems with live payments. I work with React, Next.js, Node.js, and FastAPI, and I build things that hold up under real users, not just demos. I'm new to Fiverr, not new to building things. My work is already live and running. Let's talk about what you're building. WAT (UTC+1) timezone.
