Back to original languageAbout Daniel
Are you looking for a Senior C++/Qt developer who not only maintains legacy code but transforms it into clean, testable architectures – and who delivers from day one? That's exactly my core business.
With over 17 years of C++ and more than 12 years of Qt/QML, I design scalable embedded HMI systems for series production. For about ten years, I built software at a global leader in the home appliance industry (BSH) that is now running in millions of devices – from concept to series launch.
What makes me special: I combine deep engineering expertise with a basic business understanding (IHK) and a stochastic-mathematical foundation (M.Sc.). I translate between development, product, and project management – and argue with development management as well as the executive board.
Typical mandates I undertake:
- Qt5->Qt6 migrations and MFC/legacy modernizations in productive codebases
- Design of company-wide QML component libraries as a uniform UI base across multiple product lines
- Architecture and refactoring of complex embedded HMI platforms (Qt for MCUs, Embedded Linux)
- CI/CD setup and automation of recurring development processes
As a bonus, I bring AI-assisted development (Claude Code, Copilot, local LLM workflows, CertNexus CAIP) – as a productivity lever, not a substitute for solid engineering.
