I am a mobile developer primarily working with Flutter. Some things about me:

• I grew up in Böblingen, Baden-Württemberg
• Studied at DHBW Stuttgart and IU Internationale Hochschule in Business Informatics and Software Development
• In my early career I cofounded SipTogether (later Vamos) which later got sold to Jodel and worked there as a mobile developer and Product Manager
• Later on I joined AppAkademie as a lecturer for mobile development and Baddeldaddel as a mobile developer
• Now I work primarily as a freelance mobile developer, doing (mostly) mobile development for various clients (my latest one: Ryze)

I believe that the current incumbent era of mobile applications is slowly dying out, and that the future of the (mobile) interface is more dynamic, decentralized and built on top of agentic behaviour. My interest in that area culminated in my bachelor thesis in 2025 where I prototyped a locally executed iOS Agent system with MLX and On-Device SLMs. Now, in my free time, I am working on a new project that aims to bring this agentic approach to mobile development without sacrificing the privacy of the user.
