## About

- I like building things that start as random ideas and somehow end up as products people can actually use. Most of my time goes into exploring AI, experimenting with LLMs, and building full stack applications that solve problems I genuinely care about.
- Building is how I learn. Every project is a chance to explore a new idea, understand systems a little better, and ship something useful instead of just another portfolio piece.
- When I’m not coding, I’m usually reading, writing, listening to music, or unwinding with games and sports. I’m curious by default, and that’s probably why I’m always learning, building, and chasing the next rabbit hole.

## Education

- **Bachelor of Technology in Computer Engineering** — Madhuben and Bhanubhai Patel Institute of Technology (2023–2027)

## Experience
