Building Donza.
Two decades of engineering -
pointed at one problem.
I'm Patrick. I spent twenty years in regulated MedTech - engineering medical-imaging software, leading global quality operations, auditing against the very standards I helped write. In 2026 I'm founding Donza: a family admin platform for DACH parents that dissolves the invisible mental load of school-age family life.
Donza is in active development. This site is the honest case for why I'm the right person to build it.
Proving I can ship - before betting on the one that matters.
For a decade I kept hitting real problems and thinking “if only an app existed for this.” Modern AI changed the equation: I could design and ship the solutions myself, in days instead of years. So I ran a deliberate 3-month sprint - fifteen apps, each one solving a real problem and pressure-testing a different layer of the stack. Three are live. The rest are production-ready MVPs. The sprint wasn't scattered: it was R&D to master the method before committing to Donza.
The output: a unified stack I can ship, iterate and scale on - and the judgment to know which problem is worth turning into a company.

Donza
🔧 In development · Pre-launchDonza is an AI-powered family admin platform for DACH parents. It captures the chaos of school-age family life - forwarded emails, photographed letters, pasted WhatsApp messages - extracts what matters, and handles the next step automatically: RSVP drafts, exam reminders, morning briefs, village delegation.
Current stage: Donza is in active development (P0–P3 built and in real-world testing as of mid-2026). There are no public users yet. The aws First Incubator Fund application is the next step toward launch.
The market is large (3.4M DACH households in the serviceable segment), the problem is real and lived, and the technical foundation rests on two decades of regulated software engineering and a privacy-first architecture. Everything I've built points here.
