I'm System Administrator with 10+ years of technical experience. In 1999 I started a small company focused on hosting and IT services. Since that time I’ve been working in the areas of system administration, website development, and IT consulting. I'm highly devoted to task automation, keeping infrastructure manageable, highly available and scalable. I'm also developing tools (in ruby, shell, perl) to help with sysadmin tasks. Since 2006 I’ve been working in environments where IT is critical for business and has to function 24x7 and where any downtime has a high penalty. I was a speaker on various polish IT conferences, IT trainer and generally like sharing knowledge. In my private life I like mountains and climbing. When the weather is bad I find board games (like Settlers Of Catan) a nice way to spent the evening.System Engineer @ Managing server side infrastructure for vision technology research.
