My Resume

A brief of my Qualifications



  • UNIX/Linux


    UNIX-Like operating systems live at the heart of everything I do, mastery is paramount.

  • Python


    Python is the swiss-army knife of Systems Administration; 3.5 is my flavour of choice.

  • Chef


    Chef is a common tool I've used before, it works well enough that it doesn't break so I don't get to play.

  • SaltStack


    SaltStack is my preferred automation system; I have recently been contributing to the community formulas.

  • PostgreSQL


    PostgreSQL is my preferred RDBMS, I can configure it well but advanced SQL queries are something I'm learning.

  • MySql


    I've used MySQL enough to know how dangerous it can be.

Stuff i like

  • Automation

    I love making things that do my job for me.

  • Learning

    If a project requires me to use my scripting abilities, I own it! I enjoy learning languages and creating projects.

  • Programming/Coding

    One of my favorite things to do is code. I live to create small projects and have started working on bigger projects. I mostly make things using Python and sometimes use PostgreSQL, Redis and MySQL.

I can't wait to show you what I've been working on!

Places I've worked.


Jan is incredible to work with. He is always on top of the situation, is meticulous, and sees what needs to be done. Jan was key to building the infrastructure behind The Division and making sure it ran perfectly, as well as being excellent at troubleshooting and solving any issues that came up. It was a pleasure working with Jan, and I would heartily recommend him to anyone looking for his skillset! Jan is one of the best technical leaders we've had, and it has been a pleasure working with him.

Anders Holmqvist, Technical Director, Massive Entertainment.

Jan has an incredible depth of knowledge with Linux and Unix, and has played a vital role in keeping the site and servers running smoothly. He is extremely security conscious and has been great to work with over the last 2 years.

Jake Salmon, Lead Developer, Firebox

Jan is early in his career and yet already shows a maturity and commitment that it's clear will hold him in good stead. He's keen to learn, keen to understand, and keen to deliver what's important. We're very glad to have him on board.

Mirza Manar Hussain, Head of Infrastructure, Venda

Despite Jan's young age he has already gathered a lot of experience from the Linux systems. Jan is always eager and committed to learn new thinks. I can highly recommend Jan.
