Why work with me

What sets my work apart

Built and run in production

MaxiPlein, Food Loot and HandyMake are live products that I run myself: I handle the code, the servers and, for the apps, the store releases. I bring the same care to client work.

Web and mobile, front to back

Next.js and Django for the web, React Native and Expo for mobile, with PostgreSQL and PostGIS on the data side.

You talk to the person who writes the code

No account managers in between. I answer by email and join video calls to discuss your project.

An independent technical opinion

Before you commit to a stack or an architecture, I give you my view on the options and their trade-offs.
