Message

At TomTom, I designed and delivered hybrid navigation for Android, maintaining route, guidance, and map consistency across online and offline data transitions. I also designed public Kotlin APIs and modular SDK architecture for routing, replanning, and map visualization.

I built navigation features and UI components, migrated Android modules to Kotlin Multiplatform shared modules, and created an IDE plugin for running instrumented tests. I use Claude Code for engineering work and rely on automated tests and CI improvements to support dependable releases.
