About
Personal
In my free time I can be found cycling, walking with our Wolf or playing with our 4 cats. I also have an interest in mindsports like chess, xiangqi, go and shogi. The sad part being that all of them will cost me more than one live time to master. My other free time activities include reading books, skiing and exploring all kind of topics I get interested in. I also have a passion for learning new technologies and improving my knowledge on all kind of topics.
Professional
In 2002 I got my MSc. in Technical Computer Science from the University of Twente. After graduating with a specialisation in Computer Security I started working for an Internet Company. In 2005 I made the switch to IT consultancy and have been doing that ever since.
Consultancy
I help customers design, implement, improve and automate the rollout and management of their IT infrastructure in the cloud and/or on premise.
Training
Beside my consultancy and technical pre-sales activities I am also active as a technical trainer, with a focus on teaching SaltStack and SUSE courses.

Contact
Feel free to invite me for dinner if you think we can have an interesting or mutual benefitting conversation. If you have another offer, opportunity, or introduction that might make my life more interesting you can send an email to contact (at) jeroen (dot) se. Due to my other priorities, for example playing with my cats, I’ll only respond to those proposals that are a good match for my schedule and interests.
