I'm currently a IT consultant, and I've worked 15+ years on server administration (a.k.a. SysAdmin), automation and continous deploy (DevOps), observability, cloud governance and high availability (SRE).

I know many programming languages, databases, cache/proxy serviecs, and some more. On my free time I create videogames and webapps as a freelancer.
