I build digital projects, from a single website to a whole product.

AdsCockpit: Google Ads Management, Monitoring, and Reporting SaaS

One platform replaced hand-built campaigns in Google Ads Editor, manual account checks and monthly client reports. Rules check every campaign against the agency's benchmarks, opening a task when a number slips, closing it on recovery. Clients get white-label reports under the agency's own logo, colours and name, never the software's. The team sees at a glance which campaign missed its target, which fix keeps coming undone, and which problem already cleared. Underneath: Postgres, Django, Next.js, Celery, and a nightly Google Ads sync, so rules and reports read a local copy instead of the live API.

Daily Marketing Branding and Website Relaunch

I was part of the team that redesigned and relaunched the website of Daily Marketing, a marketing agency from Würzburg: we improved the brand first, then built the website around it. It runs on WordPress with custom Gutenberg blocks, so the content team can edit every page themselves in a visual editor.

Make every location locally visible, with one central marketing strategy: a map of Germany with lines running from one central point to locations in Hamburg, Berlin, Cologne, Munich and other cities.
A new website in one hour, down from 20 hours: how a new client joins the network in four steps. Onboarding call, AI writes the text and photos are added, a feedback round with the client, website live.One update, every website: a central dashboard connected to eight websites. The shared design is changed once, and each site keeps its own text.The Astro homepage, the web framework Multisite's sites are built on: "The web framework for content-driven websites".

Multisite: Many Websites, Managed From One Dashboard

Building a new website for a local business used to take 20 hours of work. Now it takes just ONE! The new site joins a network of websites that share one design, and that is the real advantage: different designs are tested across the whole network to get the best conversion rate. The winner then goes to every site at once, while each one keeps its own text. The websites are built with Astro, the modern web technology that Porsche, IKEA, Visa and Microsoft use.

What I offer

One partner, not one project

Take one of them now and the next piece later, or all three as one plan. I would rather keep working with a company than finish one project and move on.
