Software that actually
works.

I build web applications, Office integrations, and digital products for tax advisors and financial companies — thoughtful, scalable, and to the point.

Three things. Done right.

Web applications

Full-stack web apps that scale. From UI to AI integration to database — technology this advanced is almost indistinguishable from magic.

TypeScript · React · Node · Cloud

Office integrations

Stable, performant add-ins for Microsoft Office that fit seamlessly into existing workflows. It’s time to take the red pill and see how deep the automation goes.

C# · VSTO · Office.js · Add-Ins

Landing pages & websites

Wave bye-bye, WordPress, bye-bye — Custom websites that don't look like templates. Modern, fast, and with that special something.

My Vision:
Zero Overhead.

Instead of an agency with ten different contacts, you get a direct line to someone who actually understands your needs. My focus is on the financial sector — specifically tax firms in Germany. Why? Because I have personally worked in a firm.

I don't just start coding. I listen, think along, and build solutions that survive daily use. No oversized systems, no buzzword bingo—just software that does its job.
