À propos de ce service

Are you tired of backend code that breaks under real traffic?


I'm Giang Senior Backend Engineer with 9+ years building production systems. I led backend development for 30+ live games and apps handling thousands of concurrent users.


What I build for you:

- REST APIs with Node.js and TypeScript

- Real-time WebSocket systems (chat, game rooms, live sync)

- MongoDB schema design and query optimization

- JWT authentication with refresh token flow

- Redis caching for better performance

- VPS deployment with PM2 and Nginx


Why clients choose me:

- 9+ years of real production experience

- 30+ shipped apps and games with real users

- Clean TypeScript code your team can maintain

- Fast response I won't disappear after delivery

- I ask the right questions before starting


What makes me different:

I've optimized MongoDB queries from 3s to 80ms. I've debugged WebSocket servers under 5000 concurrent connections. I've built backends supporting Web, iOS, and Android simultaneously.


To get started I need:

- What you want to build

- Your current stack (if any)

- Expected users and deadline


Message me before ordering I'll review your requirements and make sure I'm the right fit.
