Syed M Hossain
About this gig
I build powerful, scalable backend systems and REST APIs that handle real production traffic. Using Node.js and Express, I create fast, non-blocking APIs that integrate seamlessly with your frontend or third-party services. From authentication to real-time features and payments, I ship production-grade backends with proper security, error handling, and monitoring.
What's included:
- RESTful API design and development
- - Express.js or custom Node.js setup
- - Database integration (PostgreSQL, MySQL, MongoDB)
- - Authentication (JWT, OAuth, sessions) and RBAC
- - Data validation and error handling
- - API documentation (Swagger/OpenAPI)
- - Testing (unit and integration)
- - Logging, monitoring, and CI/CD deployment
- - Performance optimization and caching
Integrations: Stripe, PayPal, Twilio, SendGrid, AWS S3, Firebase
Features: WebSockets, file uploads, email notifications, scheduled jobs, webhooks
