About

Hello, I'm Avadhut

A software developer and proud geek based in Pune — India's most livable city.

I believe if we all strive to leave our community better than we found it, this world would be a fantastic place to live.

Every day I look for ways to empower people by building software. Early on, I realized technology has a significant impact on improving lives. I dove into open-source technologies like Java and never stopped learning — simultaneously completing my masters while building my professional career.

I take pride in architecture review and consultation for various open-source technologies, always searching for the latest, most interesting, and most importantly, open-source tools to solve real problems.

Open to consulting engagements, full-time roles, and technical training opportunities. Let's build something resilient together.
