Message

At N-iX, I led Android feature delivery and architecture improvements for AutoScout24, driving the Jetpack Compose migration across 15+ screens. Crash-free sessions improved from 98.8% to 99.4%, and I contributed to navigation decisions, staged rollouts, and testing standards.

Across Nike, Raiffeisen Bank, and Medtronic, I delivered Android features for large consumer apps, banking flows, and a medical wearable companion. I also built a solo ECG recording app that automatically uploaded data from a USB-connected device to Google Drive.
