I design and build backend systems that survive real-world traffic.
- ⚙️ Backend Engineer focused on scalability & reliability
- 🧠 I care about what happens in production, not just localhost
- 📚 Sharing knowledge through System Design Bangla
- Design high-scale systems (real-time, distributed, WebSocket architecture)
- Debug production issues (including silent failures and edge-case bugs)
- Work deeply with databases (MySQL behavior, performance, consistency)
- Build backend services with reliability and observability in mind
- Silent failures (e.g., MySQL writes hanging without errors)
- Observability (logging, metrics, tracing)
- Performance bottlenecks before they explode
- Debugging under real production pressure
- System behavior at scale
