01 / 07Brandon Vargas · Mobile + product engineer

I build apps you tap and things you hold.

10+ years shipping Android apps for U.S. Bank, Disney, CVS and more. These days I work across Kotlin, Swift, React and AI-native tooling — and off the clock I'm usually in Fusion 360, waiting on a 3D print.
