About Me

I started coding at age 12 — out of pure curiosity. Since 2015, I've been self-employed, helping businesses of all sizes build modern software solutions. My passion: simplifying, modernizing and automating things — whether with code, AI tools or smart home technology.

In 2024, I co-founded HubTime GmbH — a fully automated booking system with 24/7 access and PIN generation.
