Expert in RHEL, Automation (Ansible), Middleware, Containerization and more.
My professional journey began when I started as Service Desk employee, performing all kind of (workplace) IT tasks. Soon after I entered the world of System Management and went into depth on servers and everything else running in the back-end. During that time I developed a taste for Linux, which lead me to a consultancy job mainly focused on Linux and Open Source tooling.
I also encountered various Windows environments and even managed one at some point, but there was no doubt – I loved Linux and soon was seeking a role as Linux Engineer. As one, I grew towards a Linux Specialist and started to combine my knowledge with DevOps practices. Nowadays I still enjoy working with Linux platforms and tooling; physical, virtual and containerized.
At the Shared Service Centre Campus i was responsible for incident- and change management on RHEL Linux systems. I rolled out VM's with Satellite and configured them with Puppet and Ansible. I was also responsible for maintaining Jira and Gitlab and the migration of several RHEL6 systems to RHEL8

Tommy is an excellent Linux engineer for whom quality results are of the upmost importance. He shows great determination and is fully dedicated to both customers and colleagues. He’s also very funny and a pleasure to be around!Yanne Veronneau Commercially minded entre(intra)preneur
I have worked with Tommy at Avisi and I agree with the recommendations of my colleagues!
But more importantly, I think that as a colleague and also as a future client, you can trust Tommy to complete the given detailed task. Always nice to be able to trust someone when carrying out work! Also, it is special that he makes the complete and clear descriptions of how his Ansible/Kubernetes scripts work, which most technicians cannot do very well.
It was nice working with you especially considering your sense of humor :)Thijs van Amersfoort Technical Consultant & Integration Expert
Tommy is an excellent Linux / DevOps engineer. Give him a task and you know it is finished perfectly and in time. Tommy helped us tremendously in improving our Ansible provisioning system. Furthermore he was responsible for the operational work on our Kubernetes-based hosting platform. He is able to make technical difficult configurations easy to maintain and deploy, hiding the difficult parts in scripts and configurations and providing easy to use runbooks and scripts.
Tommy will make sure he is always up-to-date with the latest certifications and developments in his field so you can be sure to have the latest updates of your system.
In short a valued colleague working accurate and independent.Sander Brienen Customer Success Manager EMEA at Gitlab
When Tommy just joined our Atlassian consultancy team, we were doing installations and upgrades manual which are error prone. Tommy has been main responsible for implementing Ansible scripts for new installations and upgrades of existing environments, including customer specific requirements. This has helped us to not only be more efficient in doing these tasks but also to make fewer mistakes.
Next to that, Tommy has been responsible for hosting our customers managing a Kubernetes and Docker based environment.
Tommy is a fun and relax guy to have around in your team and most definitely will add some humor as well. It has been a pleasure working with you!Patrick van der Rijst Atlassian Certified Master
Tommy is a very valuable contributor to a team. Independent, yet a team player. He thinks "solutions", not "problems". His comprehensive knowledge is enormous - and he picks up quickly and proactively on anything he doesn't know. Never tired of answering questions, always willing to walk the extra mile.
Besides this, Tommy is a wonderful and very humorous person to work with. I'd recommend him for any team!Bart Muijzer Consultant at Sue B.V.
