Senior Android Developer at Space (Neobank), shaping a banking app’s architecture and raising test coverage to ~95%.

At Space (Neobank), I act as Mobile Architect, shaping the Android application architecture and multi-module structure. I defined the initial server-driven UI approach and implemented its first stages.

I developed and owned an Android feature module end-to-end, and set up test infrastructure and Bitrise CI workflows. This helped the team increase test coverage from almost 0 to ~80% in the first year and ~95% overall.

At InteractiveTVPlatform, I led a three-developer feature team while continuing hands-on Android development for smartphones, tablets and Android TV. Earlier, I developed Android applications and SDK components across retail, product information and secure authorization projects.
