If standard software doesn't fit your workflow, I build your custom app. With me, you talk directly to the senior developer who has built apps for millions of users. Not an agency hotline.
Your own app at a fixed price when off-the-shelf software isn't enough. Reliable AI engineering when speed matters.
Your own app when standard isn't enough
Is your workflow too specific for standard software, or do several disconnected tools fail to work together? I build your own app: from idea to launch. One point of contact, one fixed price, no surprises.

Clearly structured and personal, for businesses that value quality.
We discuss your idea, goals, and requirements. Free and non-binding.
You receive a concrete proposal with timeline, scope, and fixed price.
I develop your app iteratively with regular updates. You stay in the loop at all times.
Store publication, monitoring, and ongoing maintenance if needed. I'm here for you after launch too.
No project manager, no agency in between. You talk directly to the developer who builds your app. Example: technicians capture measurements and photos on their phone, and the rest lands automatically at the office.
From idea to MVP in just a few weeks. Start lean, learn fast, grow strategically. On a working foundation, your app grows step by step into the finished product.
Hamburg, Kiel, Lübeck, Flensburg, and all of Schleswig-Holstein: personal collaboration on-site when it matters, and just as smoothly remote across regions.
Experience from large-scale projects for companies like IBM, RTL, komoot, and AOK. I understand the requirements of regulated industries and large teams.
