What I'm looking for

I want to keep building Android apps with Jetpack Compose and modern architecture, lead teams, and ship secure, high-performance features with great UX in an Agile environment.

I’m a Senior Android Developer and Team Lead at Betsson Group, promoted to lead 10 developers after 3 months. I refactored a legacy Sportsbook app into feature-based modules, and improved navigation by migrating from multiple activities to a single-activity architecture with fragments.

I’m currently leading development of a new sports betting app using Jetpack Compose, with a strong focus on performance and UX. Previously, I built and maintained security-focused apps and an anime streaming client at gardy.me and Crunchyroll, continuously evaluating new technologies to improve development efficiency and collaborating cross-functionally to ship new features.
