I am driven by designing AI products that augment human intelligence.Before co-founding explai.com, I scaled data science teams, platforms, and products across various lines of business and industries. I move between executive roles, leading teams of hundreds and highly technical principal data scientists and software engineers in startup, scale-up and corporate settings. I build trustful partnerships with stakeholders on the business and technology side and unlock collaboration across functional silos and lines of business. I am energised by the speed and impact enabled by modern data stacks and AI breakthroughs.In past feedback, colleagues from junior to board level praised me as an active listener, creative problem solver, and a fast learner. My 2024 technical focus is Agentic AI. I am hacking in >10 programming languages, with Clojure being my favorite and Python and JavaScript at the top of my mind this year.I graduated in mathematics, computer science, and business with several scholarships, including one from Germany's largest and most prestigious foundation [1]. Having worked as a data scientist, software engineer, product manager, project manager, and consultant, my expertise is exceptionally cross-functional.[1] https://en.wikipedia.org/wiki/Studienstiftung
