Architect.

I build the systems that run a modern service business. I run one too: Taxolution, the Swiss tax practice I started in late 2017. Business-law trained, with the legal and commercial judgment to know what’s worth pursuing.

About

Founded Taxolution in late 2017, in the final year of my BSc in Business Law. Architected the proprietary client portal (built with a dev team I guide) alongside an internal automation mesh I wire up myself across Google Workspace, HubSpot, Bexio, and Taxware. 65,000+ automation runs logged. Digital-first practice serving 1,000+ clients in Switzerland. 5.0 Google rating across 168 reviews.

Also hold board positions across businesses in crypto, international trading, and accounting. Same thread runs through all of them: Swiss legal and business operations on one side, technology on the other, and I build the systems that connect the two.
