About

Currently enrolled in Bachelor's of Technology in Computer Science and Engineering. I love playing with cloud infrastructure and automating anything that I can. I mostly learn by shipping and fixing what breaks. Outside of coding, I enjoy reading, playing guitar, and swimming.

Check out my latest work

I've worked on a variety of projects, from simple websites to complex AI applications. Here are a few of my favorites.

Cosmic Engine

Cosmic Engine

A RAG experimentation platform that brings together 10+ retrieval, ranking, and caching strategies in one place. I originally built it to learn and experiment with Retrieval-Augmented Generation, and it gradually grew as I added more techniques and edge cases I ran into. As it evolved, I layered in observability and transparency to better understand how different RAG strategies behave in practice.

Hackathons

I LOVE building things

During my time in university, I attended 30+ hackathons, where intense collaboration, tight deadlines, and constant iteration became the norm. These experiences reinforced my interest in building and working in fast paced environments.
