whoami Hi there! I’m Alex, a seasoned automation consultant at Conclusion Xforce. Next to that I am the Technical Coach for our Automation (Ansible Automation Platform) focus group, and as a Red Hat Certified Instructor I deliver different Red Hat trainings on a regular basis. Linux While studying mechanical engineering at Eindhoven University of Technology, I was introduced to something new: a stack of 3.5" floppy disks and on it a Unix operating system for IBM PC, and it was free. Its name was Linux; my first distribution was Slackware and the year was 1993. And I never let go again - despite dealing with account managers who told me Linux would never be a commercially viable choice, I kept playing and working with it. Got my first Red Hat Certified Engineer certification 25 years ago, in the year 2000 when the RHCE program was freshly introduced. Re-certified on RHEL-3, 5, 7 and 9 (I have a preference for the odd numbers), I became Red Hat Certified Architect in the year 2017.

Hi there! I’m Marina, a Monitoring & Observability Consultant working for Conclusion Xforce. Next to designing, implementing and teaching best-practice observability solutions to our customers, I also enjoy giving technical demos and helping my colleagues with anything observability and monitoring-related. Since November 2024, I am also Technical Coach, meaning I am responsible for the enablement of our colleagues in the field of Observability. You can also find me on the Dynatrace community, where I post my ideas, answer questions and brainstorm with other experts. For me, the Dynatrace community is an excellent way to challenge myself and stay up-to-date. Since November 2024, I can also call myself a Dynatrace Community DynaMight.
