I have built offline-first healthcare apps in production at 300+ clinics — shipping reliable BLE, IoT, and sync architectures from architecture to deployment.

01 — About

A bit about me

I'm an Android developer with 3 years of experience building offline-first healthcare applications. I work day-to-day with Kotlin, Jetpack Compose, MVVM, Coroutines, Room, Firebase and BLE integrations with medical devices.

I've owned products end-to-end — from architecture to deployment — and care deeply about clean code, crash-free experiences, and shipping things that actually work in messy real-world environments.
