Built, measured, evidenced

For every project: the starting point, my role and the outcome — every figure with its source. Where nothing can be evidenced, nothing is claimed.

Why a photographer stayed invisible despite having an SEO plugin
Malex Fotografie had an SEO plugin, nine city landing pages and almost no local visibility. The cause was not marketing but the foundation: two plugins cancelling each other out, every section written into the HTML three times, and city pages that were copies of the homepage. Rebuilt across twelve stages and roughly 50 hours, with measurable results.

Throwing away four months of my own work — and why it was right
Rackd is a tournament platform where nobody has to install anything. Two discarded attempts as a Flutter app came first. On 11 June 2026 I wrote down the reasoning for abandoning my own codebase and starting over. This case study is about the decision, not the result.

A course platform with payments, protected video, and an audit against myself
Faszienyoga mit Melanie has its own course platform ready to go: Stripe checkout, protected video delivery, participant data under the GDPR — instead of handing a revenue share and the customer relationship to someone else's platform. Four weeks after launch I audited the running system and found three issues I had built myself.

Estate agencies maintain their properties in specialist software and then a second time on their own website. ImmoSync reads the standard export files those programs produce and keeps the website in sync automatically — each job in its own container that disappears afterwards.
