Michel Wehrli

Founder of Katalyze. Full-stack developer in Aarau.

I build complete web products alone, from the first idea to running in production. Since 2022 under Katalyze, where I work as a fractional CTO and senior full-stack developer for founders and companies. Before that, frontend lead at Eventfrog and a developer at a Zurich agency.

Through my company Katalyze I take on fractional CTO mandates and build products from idea to production.

slopmedic.com: Human Code Reviews for AI-Built Apps

2026

With AI tools, anyone can build an app today. What the tools don't say is what they left out. Slop Medic closes that gap with fixed-price code reviews. Software does the first pass, I check every finding and explain to beginners, in plain English, what to fix before launch. From business case to a live product with Stripe checkout and automated customer care took a few days.

Datapot CRM: Custom CRM Software

Since 2016

Off-the-shelf CRM didn't fit the client's processes. So I built Datapot CRM from scratch and have been extending it for more than nine years: an Angular frontend with an offline cache, a Node.js backend, Office 365 sync. The error-prone spreadsheet is history.
