About this gig

Need a Node.js developer who builds REST APIs properly, not just quickly?


I develop production ready REST APIs using Node.js and TypeScript with clean architecture, validation, proper error handling and maintainable code. Whether you need a backend for a startup, mobile app, SaaS product or third-party integration, I can build it.

What makes my approach different: Before writing code, I study your requirements, plan the data flow and choose the right architecture. No messy code or shortcuts that fail later.


What I can build:

  • REST APIs with Node.js, Express & TypeScript
  • JWT auth, refresh tokens & RBAC
  • MongoDB, MySQL & PostgreSQL integration
  • Stripe, Paystack, Flutterwave, Twilio & webhook integrations
  • AI integrations with OpenAI, Gemini, Claude and more
  • Automated workflows & background jobs
  • Validation, clean responses & global error handling
  • Well-structured and documented code


Perfect for startups, developers, businesses adding AI features, or teams rebuilding messy backends.


Every delivery includes clean source code, handover notes, and revision support. Message me before ordering if you want to discuss your project first.

Software engineer specializing in architectural modernization and secure, high performance systems. I don't just build features; I engineer scalable solutions that handle money, identity, and high traffic data. I orchestrate greenfield rewrites to replace unmaintainable legacy codebases. My core expertise lies in bridging the gap between complex backend logic (Node.js/Laravel) and responsive, pixel perfect frontends (Vue.js/React). Stack: Node.js, Typescript, Laravel, Vue.js (Quasar/Nuxt), React.js (Next), React Native.
