Senior Android Developer · Mobile Tech Lead
📍 Bucharest, Romania 🇷🇴

I am an Android Developer with 5+ years of professional experience building scalable, secure, and performant mobile applications in Kotlin and Java. I specialize in Fintech (banking, POS systems, payment SDKs) with a strong track record of delivering robust software that meets strict compliance and security standards.

Currently, I serve as the Android Tech Lead for Greenstand, an open-source environmental NGO, where I drive architectural decisions, establish CI/CD workflows, and support a distributed volunteer team.

I'm comfortable across the modern Android stack—Jetpack Compose, Clean Architecture, Hilt/Dagger, Coroutines—and highly invested in developer productivity, leveraging AI-assisted development tooling and robust DevOps automation.
