Oceanside Performance — osp-performance.de
Client project: website for a chip tuning workshop near Rendsburg that reworks engine and transmission software for cars, vans, trucks, motorhomes and agricultural or construction machinery. Seven service pages from power tuning to EGR and DPF work, four vehicle sections, an enquiry form that only asks for make, model and engine, and a full-width visual menu. The workshop's Google rating of 4.8 stars sits on the site itself, as does its WinOLS licence seal. No consent banner, because analytics run cookie-free through the site's own domain.

Bestelltheke.de
Own SaaS platform: the white-label ordering system for gastronomy. Restaurants and delivery services get their own ordering website with a custom domain, 10 cuisine designs, product configurator, delivery zones, online payment and kitchen monitor. Much cheaper than the big delivery platforms, with a small commission or flat rate, cancellable monthly. GDPR-compliant, servers in Germany.

Einmalpost.de
Own project: a service for confidential notes that delivers a secret exactly once and then forgets it. The sender types a text and receives a link; whoever opens it sees the content a single time — after that it is irretrievably deleted. Encryption happens entirely in the browser, the key never reaches the server. No accounts, no cookies, no IP logs. Plain PHP 8.3 without a framework, backed by more than 470 automated tests across three real browsers.

SmileyZone.de
Own project: an emoji encyclopedia covering 2,226 emojis, each with its own page in German and English — meaning, everyday use, code points, skin tone variants and the combinations a character actually appears in. Alongside it are tools that go beyond looking things up: an emoji downloader, a nickname generator, a chat analyser that counts a WhatsApp history entirely in the browser. Moved off WordPress onto custom PHP in 2026 without losing a single old URL — 6,013 pages are listed in the sitemap.
