About this gig

I will build a reliable, well-structured backend system or REST API using Node.js, NestJS, TypeScript, and PostgreSQL.


I have built backends that handle fraud detection for EV charging networks, real-time inventory sync across e-commerce marketplaces, payment processing with Stripe and Razorpay, and automated data migration pipelines.


What I deliver:

  • REST API with clean endpoint design
  • Database schema with proper relations and indexes
  • Authentication (JWT, OAuth, magic link)
  • Input validation and error handling
  • Third-party API integrations (payments, shipping, email, webhooks)
  • Background job processing with queues
  • Docker containerization


Stack: Node.js, NestJS, TypeScript, PostgreSQL, Prisma, Redis, BullMQ, Docker, AWS.

Every API comes with clear documentation so your frontend team can integrate without guesswork. I write type-safe code with full input validation on every endpoint.
