Summary

Cloud. AI. Code. I don't just develop software – I create solutions that work, scale, and deliver real value. With over 25 years of experience in software development and a clear focus on C#, Azure & modern AI technologies, I guide projects from concept to go-live – structured, efficient, and with an eye for what matters.

As a Cloud Engineer, AI integrator, and Fullstack Developer, I bring know-how from companies like EnBW, Zeiss, and Volkswagen – combined with a startup mentality and a hands-on approach. Whether it's classic development, DevOps automation, or intelligent AI systems (e.g., voicebots, chatbots, or code analysis using BORIS LLMs): I build what’s needed – and make sure it runs.

My goal: reduce complexity, speed up processes, and achieve real time savings with smart technology. If you're looking for someone who not only can but also does – let's talk.
