Hello, my name is Sander
I am an independent Linux author, trainer and consultant. My focus is on Linux service in enterprise environments. As such I work with SUSE, Red Hat and Ubuntu.
Apart from general Linux, I am specialized in Linux High Availability Clusters and I have advised several customers all over the world in setting up these clusters.
My other focal area is Linux Performance. I have optimized performance for many servers already, with never less than a 20% performance gain.
Teaching is one of my passions
Teaching about Red Hat, SUSE and LPI Linux is one of my passions.
I gave my first technical training in The Netherlands 1994 and nowadays I fly all over the world to help students understanding Linux related topics.
On the other hand I also enjoy teaching students via the internet in a virtual classroom where I can interact and make sure each student really understands the topics which we discuss.
From frustrated user to Best-Selling Author
My motivation for writing books presented itself in the early days when I started using Linux in 1992.
Much of the online documentation – especially in the early days of Linux- was hard to read. My goal was to translate available information into something users can really understand and can work with.
My first book ‘Novell Cluster Services for Linux and NetWare’ was published in 2006 and is still available on Amazon.
After that, numerous books and articles about different Linux-related topics such as Ubuntu and SUSE followed.
My book Red Hat RHCE® / RHCSA™ 7 Cert Guide is the first guide about RHEL 7 available across the globe!
Working in highly specialized IT environments
I’ve done some challenging consultancy projects recently. Most of these have included Linux High Availability, Virtualization and SELinux.
My typical consultancy customers are Fortune 500 customers that want an independent analysis of their situation.
They often find me because they’ve read one of my books and that already is an honor.
What I like about projects for this type of customers, is that they are using highly specialized IT environments, and I work with very skilled specialists. Together we come to a solution that improves the way they are doing business.
Initiator Living Open Source Foundation
In 2018 I wanted to give back to ‘open source’ and I decided to offer help and support to one person to acquire a Linux certification. Someone who may otherwise never would be able to start a career in open source and make an impact in their local community.
Soon after I met Santos Venter Chibenga – winner of the scholarship – the ‘Living Open source project’ was born, growing into the Living Open Source Foundation that supports open source training and knowledge centers in more and more countries in Africa.
