About

I build production mobile products and the open source tools behind them. My work spans Android, Kotlin Multiplatform, Jetpack Compose, SwiftUI, release automation, SDK design, and native products like CleanSky, BreezeKit, and iSecurePDF. The throughline is simple: ship useful software, keep APIs clean, and make developer workflows faster.

Hackathons

I like building things

During my time in university, I attended 0+ hackathons. People from around the country would come together and build incredible things in 2-3 days. It was eye-opening to see the endless possibilities brought to life by a group of motivated and passionate individuals.
