Wegscheiderstr. 5, 06110 Halle, Germany
Profile
Fullstack developer and graduated engineer (Dipl.-Ing.).
For over 10 years I have been working at the intersection of engineering and software, first
in industry at Siemens and KSB, now as a freelancer.
What I do: translate complex problems into clean, maintainable software. Whether as a
technical lead within a team or as a developer who takes a project from architecture to
deployment on my own.
My background in process engineering, thermodynamics, and industrial project
management helps me get up to speed quickly in new domains. But even without a
technical subject domain, I bring what matters:
I deliver results, on time and on target.
