About this gig

Need a clean, reliable REST API for your web app, mobile app, SaaS product, or internal tool?


I can build or extend backend APIs using Node.js, TypeScript, and Express, with clean structure, proper validation, error handling, database integration, and third-party API support.


I can help with:

  • REST API development
  • CRUD endpoints
  • Node.js and Express backends
  • JavaScript/TypeScript backend development
  • PostgreSQL / Supabase integration
  • Prisma ORM integration
  • Authentication and protected routes
  • Third-party API integrations
  • Request validation and error handling
  • API debugging and fixes
  • Webhooks
  • Existing backend feature development
  • API documentation
  • Frontend-to-backend integration


I focus on writing code that is easy to understand, maintain, and extend rather than creating unnecessary complexity.


Technologies I work with

Node.js, TypeScript, Express.js, PostgreSQL, Prisma, Supabase, REST APIs, JSON, Webhooks, Git and Docker


What you will receive

Depending on your package, you can receive:

  • Working REST API endpoints
  • Complete source code
  • Clean project structure
  • Validation and error handling
  • Database integration
