  Government ICT Centre Valtori

  Oct 2015 - Aug 2021

  This was a great viewing place to the new systems being planned, trying to guide them into fruitful outcomes, with multiple government offices as customers. We worked as teams and I greatly enjoyed the professional know-how of those I was privileged to work with. I still had lingering responsibilities from my previous positions and that helped me to have up to date technical understanding of what was possible and what was the recommended architecture of systems. I was honored by being offered this position and was glad to accept it. Show less This was a position of vast diversity of server and network related tasks, working together with multiple government offices as customers. There were smaller and bigger datacenter migrations, there was administration of several different operating system environments, with hundreds of servers. There were lingering responsibilities from my previous position at a single government office which now had become one of my customers. Most proud I am however of planting seeds of automated management, like some others did, too. My own tasks required it as manual management simply took too long time and was too error prone.
