About

Curious about how complex things break down into simple parts.

Vedant Hirekar

I'm someone with an open mind, always learning and driven by curiosity about how complex things break down into simple, manageable parts. I have always try to put myself in situations where I had to solve some kind of problem, like hackathons or improving upon some inefficiency.

My experience spans software fundamentals to ML, generative AI, computer vision, analytics, data engineering, and visualization - learned through internships, coursework, and building things. This exposure to a wide range of areas has helped me develop a holistic understanding of how different components of a system interact and how to optimize them for better performance and efficiency.

Apart from my experinces and projects, the changelog shows how consistently I ship or try to work on learning/builing something. The honest notes on every project show how I think about tradeoffs. And how this site works is a concept I tried on this website to show the engineering standards I hold myself to. And if you want to know what's up with me right now, that's literally a page.
