Custom Software Developer & Architect

I build custom software for the desktop and the web. My recent work includes a 2D rendering engine, a structural CAD editor, a DXF library, and an in-browser QBasic compiler.

A bit about me

I wrote my first program in 1998 in , mostly by trial and error. That early curiosity led me through HTML, CSS, Flash, and eventually into professional software development.

I later earned an MSc in structural engineering and spent several years in Germany building production software for SOFiSTiK AG and auxalia GmbH.

These days, I work on native Windows applications with C#, WPF, and WinForms, and build interactive web platforms with Svelte, TypeScript, and Node.js.

I enjoy solving hard problems and paying attention to the details that make software feel solid. If you need someone who can do the work well and communicate clearly along the way, let’s talk.
