I am an Android Developer with many years of experience. I have worked on numerous different projects. In my free time I enjoy making music, calisthenics, travelling with my family and programming. I have also developed two games: a retro style card matching game called imago, which is fully made in Jetpack Compose, and spellloom – a roguelike dungeon-crawler with deep spell-building mechanics made in Unity.
