👋 About

I'm a final-year engineer who likes the backend: designing REST APIs, auth flows, and data models that hold up when real users show up. I build full-stack apps on PERN / MERN, and I'm now going deeper into cloud and AI-integrated backends (FastAPI, Docker, CI/CD, AWS).

  • 🔭 Building now: an AI-powered PR review bot — GitHub webhook → FastAPI → LLM reviews the diff → results in PostgreSQL, Redis for caching / rate limiting, Dockerized, shipped with GitHub Actions to AWS EC2
  • 🗺️ Up next: an AI-triaged civic issue reporter for Bengaluru (photo + location → issue classification → auto-routing to the right department)
  • 🌱 Learning: FastAPI · Redis · GitHub Actions CI/CD · LLM API integration
