About

Hey, I'm Vivek.

I'm a full-stack developer with a knack for product. I've worked at multiple YC-backed startups building AI agents, developer tools, and early-stage products. I like solving real problems with fast, simple solutions.

I graduated with a Bachelors degree in Applied & Computational Math and a specialization in AI applications from the University of Southern California.
