I build web applications people enjoy using, from planning to production. Platforms that bring people together: to date, bid, sing, celebrate and work.
/* about */ who's building here
Hi, I'm David.
Full-stack developer since 2013, from tiny one-pagers to enterprise solutions. Today I'm a senior engineer at Pflegehelden working on CRM systems, and as a freelancer I build complete platforms from scratch. My workflow is AI- and agent-optimized: agents handle the routine, architecture and quality stay with me.

The AI Crew
I don't just work with AI, I work with a crew. Agents refactor, test and document in the background while I own architecture, reviews and quality. That's how speed happens without care falling off the table.
~/crew · agent log · live
In practice: I work spec-driven. Requirements and acceptance criteria come first, then an agent loop harness powered by the latest LLMs works against them until everything is green, tests and docs included. Every line still gets reviewed by me.

CEO @ Socialmatch
David has been successfully taking care of the frontend and backend of my websites for over ten years. He brings a lot of experience, and it shows in the high quality! What stands out most is his reliability and availability. Even on weekends he steps in on short notice when something important needs to be done.
Engin Erhan
CEO @ trivia of life Ltd.
We have been working very successfully with David for 2 years. He took over the complete project management and helped build the entire infrastructure, so we were able to launch our platform successfully this year. Since then he has been supporting us continuously, solving our problems and the challenges of day-to-day business within days or even hours. We are very satisfied and will continue working with him!
E. Gümbel
CEO @ Leuchtfeuer Digital Marketing
David supported us as a TYPO3 agency in developing and maintaining our client projects. He got up to speed with our tech stack very quickly and was a great addition to our development team. His deep expertise was reflected in the quality of his work.
Frederik Frey
CEO @ BINAERIX
As an IT company, our biggest challenge is finding reliable developers who meet our quality standards. David delivers his tasks within deadlines and takes feedback to heart. When difficulties arise, he reaches out proactively and independently proposes constructive solutions.
Felix Hahmann
Co-Founder @ XAIN AG
David actively supported XAIN's early phase with his web development expertise. Beyond our own web presence, he held a technical lead role in client projects, which he carried out with great dedication and professionalism paired with excellent expertise.

See for yourself.
References are good, touching is better. That's why the sandbox exists: VoltGrid, an invented product, thought through end to end. From the spec through architecture, a running API and UI kit to tests and deployment, everything clickable, much of it actually running.
