About Me

I started coding in 2011 and never stopped. Today I work at Wealthior Group, a Swiss holding company building innovative ventures across Tech, Travel, Real Estate, Media, Web3, and Investments.

My work sits at the intersection of solid engineering and practical business thinking. I write code that runs in production, not just demos. Every project gets the same attention whether it is a small landing page or a complex platform.

Based in Zug, Switzerland, I work with clients around the world. Most projects run fully remote. If you need someone who can take a rough idea and turn it into working software, I would be happy to chat.
