My primary areas of expertise are IT infrastructure and the interface between computers and physical systems.

I see exceptional abstraction ability as my greatest strength, enabling me to find promising solution candidates in any complex solution space. Due to my vast, cross-domain hands-on experience, I can then develop evaluation plans and perform practice-oriented evaluations.

Communicating ideas, findings and possible difficulties to engineering, management and customer addressees is another significant part of my skillset.

My practical experience includes the following areas:
  • Enterprise IT environments, virtualization, networking, microservices architectures, cloud native design and containerization
  • Embedded systems (hardware design, circuit design, high speed PCBs, design for manufacturing, FPGAs, microcontrollers, industrial I/O)
  • DevOps and workflow development - tooling and automation of development-, test- and deployment procedures
  • Automation technology and customized machinery
  • Product design in the aspects of hardware and software
  • Mechatronics and CAD
Please find a detailed list of my areas of expertise in the document "Detaillierte Kenntnis-Übersicht".

Familiarization with new subject areas is natural for me and I'm very interested in new challenges.

Feel free to contact me if you have any questions regarding my profile.
