Summary

I have been working for many years as a freelance software developer with a focus on full-stack development – from classic .NET/C# backends to web interface design to modern React frontends.

What excites me most: making complex things tangible – whether through data visualizations, dashboards, or clear, strong messages.

Besides the tech, I have a good sense for language and impact. I don't just develop functional software, but also ideas that reach people on an emotional level – in words and interface.

Whether it's visual reports, trading tools, or communication concepts: I think interdisciplinary and bring structure and creativity together.

I'm open to freelance projects in frontend/visualization, API/backend architecture, and creative special projects with impact.
