I am an Open Source enthusiast and work as a DevOps Engineer, Site Reliability Engineer, System Administrator, or whatever you call it nowadays. I got a degree in Information Technology, but most of my knowledge is self-taught.

Currently, my focus lies on high availability systems, GNU/Linux, mainly Debian, security, automation (Puppet, pipelines, etc.), databases, and everything around web hosting. In general, I enjoy learning about computers, automation, security, and a bit of entrepreneurship.
