I am a Hamburg-based mobile developer with experience spanning Flutter, Android and Kotlin Multiplatform. My work has covered e-commerce for millions of OneFootball users, live video and timing for F1 TV, banking onboarding, connected-home entertainment and fitness experiences.

I combine hands-on engineering with architecture, product delivery and technical leadership. Recent work includes a remotely managed Flutter storefront, supporting backend tools and AI-assisted development, while independent projects such as ReelMatch keep me close to the full product lifecycle.
