Senior Linux/UNIX Systems Engineer & Freelance Open Source Professional
Hi! My name is Armin, and Iām 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 am deeply passionate about the command line, automation, and the UNIX philosophy. My work focuses on terminal-driven workflows, system performance, reliability, and creating clean, maintainable solutions based on simplicity and technical excellence. Throughout my career, I have gained broad experience across diverse environments, ranging from enterprise infrastructure to modern open source desktop systems. My approach is guided by stability, minimalism, and a strong focus on understanding the underlying technology rather than relying on specific products or proprietary ecosystems. Driven by curiosity and a desire to understand how systems work beneath the surface, I continuously explore complex technologies and expand my expertise in areas that truly interest me - especially UNIX & BSD, automation, and IT security. I enjoy deep technical exploration and applying that knowledge to build practical, reliable, and thoughtful solutions. Rather than focusing on products, I focus on the technologies and principles behind them. This perspective allows me to continuously grow my knowledge independently of vendor ecosystems and avoid unnecessary lock-ins, creating solutions that remain flexible, sustainable, and future-proof.
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.

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 ;-)
