Building software

At a glance

I have built software for more than twenty years. Today AI coding agents write most of the code. With them I build MVPs and production-ready software in a short time, above all for data management and workflows. A company gets working software early and can test its idea with real users.

Agentic coding

Claude and Codex write the code. They work under rules that a machine checks before each change. My part is the data model, the workflow behind the software and the review of every result. The same rules apply to the MVP and to the production version.

WordPress, then leaner systems

For many years I was a WordPress expert. Today most of my former WordPress projects run on other systems. The sites load faster, and there are no plugins left to patch.

From 2016 I built company websites and online shops on WordPress. The websites of an insurance group ran on it through several launches and relaunches. I wrote my own plugins and templates. Multisites and multilingual installations were part of the job.

Since then I have moved most of these projects away from WordPress. This site is one of them. Until September 2026 it ran on WordPress. Now it is a static Astro build, and the server delivers plain HTML. No database sits behind the pages. Claude did much of the migration work as a coding agent.

What a client gets from such a move: pages that load fast and carry their text in the HTML. Search engines and AI assistants can read that text without running a script. Updates no longer depend on a plugin vendor.

Frontend and servers

The frontend is HTML, CSS and JavaScript. I have focused on it since 2012. My tools then were jQuery and Bootstrap. Angular followed in 2019. The layouts are responsive. I test them at phone width and at desktop width.

The Linux servers underneath are ones I set up and run myself. Code lives in Git, organized with Gitflow.

How it started

At 15 I wrote my first programs in Basic and Assembler on an Amiga. School brought Pascal. From 1990 to 1997 I ran mailboxes and exchanged data by modem. In 1997 I learned ColdFusion. Some years later I switched to PHP. Since then, I have also worked on projects written in Go, C#, Python and TypeScript.

I am passionate and I feel great gratitude for everything I can do. Nothing can stop me from reaching the best results.
