About Me
I'm a Backend Developer focused on building API-driven applications and backend systems. My primary stack is Go with experience building REST APIs, authentication and authorization, database-backed services, background processes, and realtime features using WebSocket. I focus on building backend systems with clear architecture, reliable data handling, and maintainable code.
- Primary Backend: Go, Gin, REST API, JWT, WebSocket
