About Me

I am a developer with a broad skill set and experience leading small teams. I specialize in iOS and web-based app development (full-stack), from designing APIs to deploying data-intensive applications.

I am an alumni of the University of Pennsylvania's International Guest Student Program (Philadelphia, PA, USA) and the Apple Developer Academy, and I am currently a part of the Apple Developer Institute for AIML.

I also won the 2026 Swift Student Challenge competition from Apple and was named as one of the 50 Distinguished Winners worldwide, for which I was invited to attend Apple's WWDC26 event in Cupertino, CA, USA.

Outside of work, I am a tech hobbyist, running my own mail server and other self-hosted services for personal use.
