3rd Year CSE Student. Co-founder of Azeorex. Building production-ready AI SaaS that bridges the gap between complex engineering and human-centric design.

The Story

Beyond the Code

A glimpse into the mind of a developer who builds for impact.

I build ecosystems,
not just code.

I'm a 3rd year CSE student who doesn't just code—I build ecosystems. From co-founding startups to shipping production-ready AI SaaS, I bridge the gap between complex engineering and human-centric design.

The Difference

Unlike many students, I've lived the startup lifecycle—from co-founding to handling production users.

The Goal

Currently seeking internships where I can contribute to high-impact products and push the boundaries of AI.
