Hi, my name is Jan Kapellen, and as you've already learned on the start page, I solve issues in large linux setups. Some of them with automation.


My industry background is mostly in digital advertising. About half the time with email marketing and the other half with display ads. My most recent expieriences range mostly around automation and management of that automation. I also had some very recent contact with data center appliances and video streaming services.

I also develop small webapps. My latest proof of concept was a small React.js app that can pull your current location and display it. It's not something very fancy, but it might help in situations where you are lost. You can view the result on

I worked on projects utilizing the following programming languages:

python, perl, php, javascript, clojure, bash

I have set up and administered the following software:

Ansible, Puppet, Confluence, Jira, Jenkins, Couchbase, Hadoop (CDH <5), Redis, Qmail, Postfix, Powermta, Powerdns, Bind, Unbound, Solr, Kafka, Flume, Nginx, Apache Httpd, Ha.d/ldirector, Haproxy and a lot more small bits and bobs that I already have forgotten about.

I mainly work on RHEL and Debian based operating systems.

I have worked mainly in Kanban based project environments.

I have a very broad knowledge about possible software solutions but a somewhat narrow one when it comes to questions of security, network and hardware.


As for my hobbies, I love tinkering with Raspberries, I play a lot (probably too much) violent fps video games (Planetside2, Far Cry, Dying Light, aso.), I love audiobooks and I have a soft spot for neuroscience, sociology, philosophy and artificial intelligence.

My most read (or well, mostly heard) authors of the last years are David Eagleman for non-fiction and Daniel Suarez for fiction.

I am also super hyped for some of Netflix original programming, for example Stranger Things is probably one of my Top5 TV Series of all times.
