About Me

Jeffrey Koetsier

I am a Linux Specialist with over 15 years of professional IT experience.

In 1999 I started my Unix/Linux career with an upcoming ISP. Since then I've been working for a variety of companies in The Netherlands and gained a lot of experience in the different fields of IT.

My technical interests and skills are primarily in the area of Automation, Distributed Systems, Metrics, High Availability, Cloud Technology and Microservices.

Besides tech-stuff: I like to travel, do sports and motorcycle trackracing.
