What I'm looking for

I'm open to remote Android engineering roles with US/EU time-zone overlap, where I can build production mobile apps and lead architecture, quality, and delivery.

I've built and shipped six production Android healthcare and telemedicine apps at Universal Digital Healthcare, serving patients and providers across multiple US clinics.

I delivered HIPAA-compliant EHR, remote patient monitoring, messaging, push notifications, Vidyo.io consultations, and Stripe, Braintree, and PayPal checkout flows in Kotlin and Java.

I owned Android code review, architectural direction, and 15–20 Play Store releases each year, while mentoring developers on Kotlin, Jetpack Compose, and MVVM.

I'm currently building a Kotlin and Jetpack Compose ride-hailing and luxury chauffeur app with live tracking, fare estimates, booking flows, offline-safe state, and battery-aware location updates.
