AI

I use AI as a tool throughout the development process. It takes over repetitive tasks and helps with research and prototyping.

This means projects can be completed sooner, and even large projects can be realized with significantly fewer resources.

AI also serves as an additional check to detect bugs and special cases, so the code ends up cleaner, more consistent and easier to maintain.

I always review the final result myself and take responsibility for it.

Testimonials Testimonials

Stefan developed a sales app with AI integration for me, and I am completely satisfied with the result.

What I particularly appreciated about working with him: Stefan works in a very structured, realistic and solution-oriented way. No empty promises, but clear assessments, comprehensible planning and an implementation that really holds up. […]

That is why I can recommend Stefan without reservation! For anyone looking not just for a developer, but for a real partner for their digital idea.

Review on Malt, July 2025 · Translated from German

Stefan implemented our own website exactly to our specifications. He was very reliable and always friendly throughout all communication. His commitment to realising complex and challenging requests and finding solutions for them deserves special mention.

He always kept to the timings. The handover of the website also went smoothly. We can recommend Stefan and would work with him again.

My motivation My motivation

My goal as a freelancer is to deliver a high-quality product and to do so as efficiently as possible. The fascinating thing about web development for me is the interplay between design and programming, as well as the possibilities that have emerged through the use of AI.

Expertise Expertise

After my training as an IT specialist at BASF IT Services, I worked in various IT companies. I have been working in web development since 2020. Today I work as a fullstack developer: I build the frontend, backend and database, and I also take care of hosting and deployment on Linux servers. I also develop apps for iOS and Android.

Leisure timeLeisure time

When I'm not busy coding, you can find me on the saddle of one of my various bikes. I also enjoy traveling and have a passion for water sports such as swimming, surfing and snorkeling.
