01 - about

about_me();

I'm a Full Stack Engineer from Mumbai who builds things that actually ship.

Two internships. Multiple deployed products. One competition win. Currently in my final year of B.E. in Information Technology.

I specialize in MERN stack systems with a backend-first mindset - what excites me most is the intersection of practical backend engineering and AI integration.

Whether I am architecting robust database schemas for production systems, optimizing API retrieval times from 45s down to 50ms, or integrating LLMs - whether frontier APIs, locally-run open source models via Ollama, or Groq-hosted inference - my focus is always on performance and architecture. I don't use AI as a buzzword - I ship it.
