About

I am Harsh Kapadia (he/him), a Software Engineer currently based in Austin, TX, USA. I am interested in the Web, exploring the internals of tools and technologies, and communities.

I have been enjoying building software tools and learning more about servers at my current role at AMD, while trying to lead a more disciplined and balanced life.

I like building projects, and talking and writing about my learnings.

I started Our Tech Community (OTC) in 2020 and we regularly conduct events for all of us to learn more.

I love books, music, YouTube and Bird Watching.

Feel free to get in touch with me!
