Finally a website that looks like craftsmanship instead of a stock shop template. Roberto listened closely, agreed on clear phases, and translated my style onto the web.

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.

Through Wealthior Labs I deliver fixed-price packages for Swiss SMEs: premium websites, AI workflows and internal tools. Based in Zug, I work remote, preferably with clients in Switzerland, international possible.
