## About

```text
As an Open Source Software Engineer, I contribute to Celery, Django, Hugging Face Transformers, Redis, and vLLM. My work includes fixing Celery task hierarchy loss, refactoring Django migration serializers, and integrating reasoning tool-call extraction in vLLM.

For FluxMesh, I built a resilient task orchestration platform using atomic Redis Lua state transitions, with automated recovery for zombie workers and a Dead-Letter Queue replay engine.

I built EdgeFlow, a FastAPI reverse proxy that reached 2,700+ RPS with 11.7 ms P50 latency. The project also includes a Redis sliding-window rate limiter and SHA-256 caching with Circuit Breaker failover.

With DevPilot, I created an AI codebase analysis platform using AST-aware chunking and PostgreSQL vector search, achieving 100% RAG recall. I'm studying Information Technology at IIIT Bhopal and have earned Kaggle silver medals and badges.
