Crafting mobile experiences
people love to use

I'm an Android Developer with 3+ years of experience building consumer-facing apps in Kotlin and Java, with a combined Play Store reach of over 10.5 million downloads.

I've delivered end-to-end features across video streaming, AI photo editing, and real-time multiplayer platforms — including a self-published Play Store game built on Firebase, AWS Lambda, and Google Gemini AI. I care deeply about clean architecture, smooth UI/UX, and shipping products that actually move the needle on engagement and retention.
