I’m an Android engineer who ships production apps end to end. I build with Kotlin and Jetpack Compose, taking strong ownership of mobile UX, location features, reliability loops, and release pipelines.

At Runking, I shipped a production Android fitness/social app using Jetpack Compose, Material 3, Hilt, Room, WorkManager, and Maps Compose. I integrated Firebase Auth, Firestore, Cloud Functions (Node 20/TS), Storage, FCM, Crashlytics, Play Integrity, and Play Billing, supporting features like GPS tracking, H3 territory capture, clans, streaks, rewards, ranking, onboarding, and privacy zones.

I’m careful about quality: I run QA loops with emulator and ADB/logcat, conduct security reviews, and handle regression testing plus automated APK pipelines. I focus on building feedback loops that keep releases stable and trustworthy.

Before that, in Systems and Data Support (Microsoft, Remote Argentina), I did remote network data-flow analysis, data pipelines, troubleshooting, and documentation. I’m comfortable collaborating asynchronously and bringing a systems mindset to mobile engineering.
