ABOUT ME

Android Developer

I build Android apps that actually scale. 9 years solo dev. Built 2 apps from scratch to 1M+ downloads each, maintained 5-6 app portfolio (90M+ combined downloads) for the last 5 years.

I own complete cycles - architecture, implementation, deployment, maintenance. Performance-critical work: offline-first apps, audio processing, kept crash rates under 1%. Used XML over Compose because speed mattered more than hype.

Kotlin, MVVM, Coroutines, Flow in production at scale. Room, Retrofit, Firebase. Top 1% Stack Overflow (14k rep, Android). Ran Kotlin workshops at GDG events.

I ship fast, communicate clearly in English, don't need hand-holding. Been solo for 5 years - that's both good (can own features end-to-end) and bad (limited CI/CD practice, no recent team experience). Ready to work with actual teams again.

Want teams that care about shipping working products.

Implemented responsive UI that scales across all Android devices, improving user retention
Integrated Firebase Analytics, Crashlytics, and in-app purchases
Managed Play Store optimization: ASO, user feedback response, release cycles

Technical Stack:
