Plumbing and heating service
The old site took six seconds to load. On a phone, people left before anything appeared at all.
Rebuilt, with automated enquiry handling behind the scenes. The site now shows up in just over a second.
Master electrical contractor, Duisburg
A certified electrical contractor doing solar, smart home and installation work, with no website at all — enquiries came only through word of mouth.
A web presence with a contact form and technical search optimisation. Enquiries now also come from people who had never heard of the business.
Non-profit foundation, Solingen
A nature conservation foundation that wanted to maintain its own content and blog posts — without commissioning someone for every change.
Deliberately a WordPress solution rather than a custom build. It fits the need, fits the budget, and runs without us.

Stores no personal data: aggregate counters only, expiring after 90 days, IP addresses hashed throughout. Access rules by IP range, network (ASN) and country are evaluated before the risk engine. This is the same tool running in the form on this site.
A sovereign European network that puts quality over reach — for individuals, universities, public authorities and companies. Currently in beta access.
Database, media and live video in European data centres, no ad trackers and no shadow profiles. Outside services are being replaced one by one with in-house ones: reCAPTCHA is already done, our own analytics is in progress.
A platform for restaurants, salons, trades and local businesses: links, offers and menus under one address, with a QR code for the venue.
Multi-tenant with a trade directory, its own design system and admin area — built for the very businesses I also make websites for
A shop for custom-designed mugs — with a designer and live 3D preview, made in Langenfeld.
Product configurator with 3D view, payment via Stripe including Apple and Google Pay, DHL integration with tracking

A quiz platform where many people play against each other in real time.
