01 About
Native Android, taken all the way to production.
I’m a senior Android engineer with over eight years of experience creating mobile applications with the Android framework in Java and Kotlin.
I’ve taken products from an idea to a Play Store release — ride-hailing, healthcare booking, vendor tools, and field data collection — and I publish libraries other developers can drop into their own apps.
I lead HackerCode Community, mentor junior Android developers, and contribute through the Google Dev Library.
