No. Most of my clients are CEOs, product managers, or marketing directors — not developers. I work together with you to create the technical specification.
iOS, Android, Web (PWA), cross-platform with Flutter or React Native, as well as specialized solutions with Unity 3D for 3D and AR applications. I typically build so that one app runs on multiple platforms simultaneously.

Data privacy is built in from the start — Privacy by Design. All apps are developed GDPR-compliant. If needed, also with certification (e.g., digital health apps, CE). German servers, German contracts.
You do. I transfer all rights, the complete source code, and the documentation. German contract, NDA as standard. You can have the app further developed by another developer at any time.
Yes, optionally. Many clients use my maintenance contracts for regular updates, OS compatibility, and technical upkeep. But you're not locked in — I can hand over the project completely if needed.
Absolutely — I actually recommend it. Start with an MVP and test the market. If it works, we scale together. No risk, no all-or-nothing.
No agency overhead. You work directly with me — the developer who builds your app. That means faster communication, fewer misunderstandings, and more of your budget going into actual development.
