I build production-grade distributed systems and AI platforms focused on:
✅ High concurrency systems (1000+ concurrent users)
✅ Low latency real-time backend (< 100ms)
✅ DevOps & observability-first engineering (AWS, Site24x7)
✅ AI workflows (LangChain, LangGraph, RAG, Multi-agent systems)
I don't just build features — I build systems that scale, stay reliable, and remain maintainable for teams.
