About me
To be at my best, I need complex technical problems and challenges were I can bring in my 20+ years experience as technology generalist. I'm an Open Source Enthusiast and Contributor. A Passionate Engineer with a strong hands-on mentality. A problem solver, experienced Architect and People Manager. A Leader who takes Ownership and is always eager to learn and adapt. My Super Power is the ability to equally work Strategic and Operational. Seamlessly from the Big-Picture down to technical implementation details.
My professional career started in 2002 and has always been IT focused. I have a strong background in Architecture, Engineering and Operations. Adopting new Technologies and DevOps paradigms as well as Automation, Programming and Mentorship are an integral part of my work.
I'm passionate about Linux, Kubernetes, Infrastructure, Coding and Automation. I know multiple programming languages and dive deep into a new codebase quickly. I systematically troubleshoot issues and debug code and prefer to automate re-occurring tasks. I'm a generalist with a very broad skill set. I would describe myself as an expert engineer and intermediate software developer.
Learning and Development is important for me, technical trainings and certifications allow me to to improve and validate my skills. In recent years I became 18x SUSE, 7x AWS, 3x Kubernetes, 5x Red Hat, 2x Linux, 2x Azure and 5x SAP certified. With a track record of more than 70 technical certifications throughout my career.
