Profile

With over 25 years of IT experience in various roles, I am currently a Senior DevOps Observability Lead at KPN, the largest telecommunications provider in the Netherlands. My mission is to define and implement observability solutions that support internal stakeholders’ requirements, provide a central observability platform across multiple data centers and cloud regions, and support a modern incident response workflow.

As a DevOps expert I have extensive experience in integrating and adopting best-of-breed solutions for observability, using technologies such as Kubernetes, Elastic, Grafana, Prometheus, and more. I also have a strong background in cloud solutions, having worked with AWS and Azure and OpenStack for private cloud. I am passionate about IT, always eager to learn new things and committed to delivering high-quality solutions that improve the reliability and performance of systems. I also enjoy mentoring others, solving problems, and communicating clearly and effectively.

Interests

I like to experiment with new technologies to play with my homelab which I use (also) to collect and store IoT data in a Victoria Metrics cluster running on a private Kubernetes cluster. Grafana is used as the presentation and alerting layer.

Occasionally I write posts on my technical blog.

One of my pet projects is to track consumed media (movies, TV series, book) to explore their relation and watching sequence.

Since 2022 I organize my ideas and tasks with Obsidian after trying Notion for almost a year.

As often as possible I’d like to travel and stay in touch with nature.

My favorite sport is table tennis and I played competitively until 2014.

Reading (books / comics)
Movies
TV Shows
Traveling
Hiking
