Product engineering with AI and platform depth

My work spans internal tools at SAP, startup product cycles, and community education projects. I focus on shipping useful systems quickly while keeping architecture maintainable.

I am currently exploring model-context tooling, agent-driven testing, and interfaces where people and AI systems can collaborate effectively.
