I build digitalproducts that resonate.
Software engineer with 9+ years of experience. React, TypeScript & Node.js — based in Halle (Saale), Germany, working with clients across the DACH region and remote.
9 years of code & product.
From idea to deployment — I build digital products and guide them through the entire lifecycle.
I have been building digital products since 2017 — starting as a part-time developer, then leading engineering at an agency, and now working as an independent freelancer. Over 50 projects shipped from concept to production, 15+ apps published to the stores, and clients across many industries supported in turning their digital vision into reality.
As a freelance software engineer, I bring this experience directly to your project. No overhead, no agency markup — senior engineering with a modern stack of React, TypeScript and cloud solutions. From high-performance web apps to native mobile applications.
