Hi, I'm Franz

I build new websites, web apps, and mobile apps with one core principle: simplicity beats complexity. From prototype to product, I use fast feedback cycles and low-maintenance technologies.

My digital business card

From idea to launch, I develop new digital products from the ground up – from quick prototypes to complete applications. If you want to build a new website, web app, or mobile app, I help you develop it step by step into a market-ready product.

Have a project in mind? Feel free to write to me – or read on to learn more about how I work.

How I work

Good software comes from fast feedback, not perfect planning. A prototype in 4 weeks brings more clarity than 3 months of planning. That's why:

  • I build a testable version as quickly as possible
  • I use modern tools to accelerate development (AI-assisted development, proven frameworks)
  • I stay flexible – requirements change, that's normal

When choosing technologies, I balance development speed, maintainability, and performance. I prefer solutions that keep runtime and maintenance costs low: static websites, serverless architectures, specialized services for standard tasks.

Simplicity beats complexity – especially in the beginning. The best solution is the one that actually works.

What I've built

A few projects I'm currently working on or have worked on. From AI-powered search to end-to-end encryption – here you can see what's technically possible:
