You will get Build Scalable Backend API with NestJS, PostgreSQL & WebSockets
Project details
You will get a scalable, secure, and production-ready backend system built with NestJS or Express.js, using PostgreSQL or MongoDB with Prisma, TypeORM, or Mongoose. I specialize in designing clean architecture APIs that are easy to maintain, extend, and scale as your business grows.
Unlike basic CRUD implementations, I focus on structured backend engineering — including authentication (JWT/OAuth), role-based access control, database optimization, real-time features using WebSocket or Socket.io, and third-party integrations such as Stripe payments.
Every project is built with performance, security, and long-term scalability in mind. I follow modular architecture principles, proper validation, centralized error handling, and environment-based configuration to ensure your backend is production-ready.
You will receive clean source code, documented APIs (Swagger or Postman), and clear deployment guidance. My goal is not just to deliver working code — but to deliver a backend foundation that supports real business growth.
