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.

We define what success looks like. Clear goals, realistic timeline, no hidden costs.
Build
Regular updates so you always know where things stand. No surprises at the end.
