Web Development
I build websites, shops and small digital systems — from idea to online. Fast, clean, and in a way you can understand yourself.
You're looking at one already
This site went from first idea to live online in about a week — with AI as a partner and a well-prepared data base from ten years of work. It runs on any device, is self-hosted, bilingual, cookie- and tracking-free. If you want to know what's possible: just scroll the site.

What's possible
Four rough buckets. If what you need doesn't quite fit — just ask.
Websites & shops
From a single-page site to a full e-commerce shop. Cleanly built, fast, runs on any device. Domain, hosting and email setup are part of the deal, if you want.
Hosting & infrastructure
Own servers, reverse proxy with HTTPS, backups, mail aliases, small Raspberry-Pi setups. If „in the cloud“ feels too vague — I look after the actual machines.
Automation & AI integration
Letting shop ↔ ads ↔ shipping ↔ logistics talk to each other. MCP servers, AI agents, small dashboards, chat- or phone-bots, automatic email replies, image recognition. If something is costing you time that no human should really be doing — it can probably be automated.
Custom systems & experiments
If no existing tool fits: build your own. Start small, learn, keep building. Web3 and crypto integrations welcome — there's real movement there right now.
Who's doing this
Computer science degree, RWTH Aachen, focus AI & VR. My skill isn't writing code — my skill is understanding systems and building them cleanly. With AI agents as co-workers, that's ten times faster today than two years ago. I try things cheaply, double down on what works, and I know enough people to reach the right ones when I'm stuck.
Personal projects
henny.info
The site you're on. Astro, static HTML, self-hosted fonts, cookie- and tracking-free. Quiet and robust — what a calling card should be.
GRID VR Browser
A web browser, built in Unity for Meta Quest 2. Bachelor's thesis, RWTH Aachen. In a 24-participant study, 24 % faster at re-finding information across tabs than the standard browser at the time. Grade 1.0.
berger.koeln
Family project in the same playbook as this site. Clear structures, fast setup, same shape.
Real numbers
Actual screenshots from client projects — coming. Anonymised, so no one gets exposed.
Examples on request
I'll happily show you specific shop and project references when we talk — much of it is still in progress or password-protected, and I think it's fair not to name clients without asking them first.
Got an idea?
Send me a line. I'm especially open right now to interesting projects — including crypto and Web3.
