What the site contains

The homepage is organized into a small set of sections, each with a clear purpose.

The projects listed

The Projects section showcases several AI-driven products, mostly in German and English:

When this site is useful to you

• You are looking for an AI engineer or collaborator and want to see concrete shipped products rather than a résumé alone.
• You want to understand his technical range — from deep learning in medical diagnostics to SaaS tools built around AI.
• You are interested in his writing and want to read the blog.
• You want to get in touch about cooperation, which the site explicitly invites.

One caveat: the site's skill counters display placeholder-style values (for example, "0+ years of experience" and "0k+ users daily"), so treat those numbers as unverified and rely on the project descriptions and career timeline instead.
