Senior Linux/UNIX Systems Engineer & Freelance Open Source Professional
Hi! My name is Armin, and I’m a Senior Linux/UNIX Systems Engineer and Freelance Open Source Professional with more than 15 years of experience designing, maintaining, and optimizing reliable infrastructure, developing robust automation, and building efficient solutions for *nix environments.
I’m passionate about the command line, automation, and the UNIX philosophy. My work focuses on system reliability, performance, and maintainability, with an emphasis on simple, efficient solutions built on a solid understanding of the underlying technology. Throughout my career, I’ve worked across diverse environments, from enterprise infrastructure to open source desktop systems. My approach is rooted in minimalism, technical independence, and a preference for understanding how things work rather than relying on specific products or proprietary ecosystems.
Driven by curiosity, I continuously explore technologies that interest me, particularly UNIX and BSD, automation, programming, and IT security. I enjoy digging deep into complex systems and turning that knowledge into practical, reliable solutions. I believe in technology that remains understandable, adaptable, and free from unnecessary vendor lock-in. By focusing on fundamental principles rather than individual products, I build solutions designed to be maintainable, flexible, and sustainable.
I'm a passionate musician, DJ and visual computer artist who has worked professionally over 15 years with Linux & BSD. One of my primary goals is crafting beautiful, functional, and secure IT applications and appliances that work reliably and are a joy to use. My expertise spans across infrastructure design, configuration management,
scripting, provisioning, and deployment automation. I'm a minimalist at heart who loves to start from scratch and to build solutions from the ground up.
I believe in the power of lightweight software, intuitive design, and seamless user experiences. When I'm not coding, you can find me exploring new operating systems, free software, programming languages, contributing to open-source projects, or making music and visual art.

Born in Bremen, Germany, in 1980 - back when atmospheric CO₂ was a modest 338 ppm. Spent eight months in Dublin and went to school in Duisburg. Once lived in a flat with fast internet but no warm water (priorities). Native German speaker with fluent English. Currently based in Berlin and open to remote opportunities.
I'm always excited to talk with people about crazy ideas and I love to hang out on IRC. If you feel bored, or you simply want to test your fresh new mechanical keyboard and type away, drop me a /msg ;-)
