Senior🎓
Top SchoolWerner Dijkerman is a Platform Engineer and freelance DevOps specialist with 12+ years of experience building cloud-native platforms, automation and observability for enterprise customers. He focuses on Kubernetes, Terraform and AWS, and has deep hands-on expertise in monitoring and security stacks including Zabbix, Prometheus, Wazuh and OpenSearch/Elasticsearch. A practical automation advocate, Werner has strengthened testing and CI workflows across Ansible, Molecule and Testinfra and contributed GitLab integration modules to core Ansible and testing improvements to widely used projects like ansible/molecule. He also reviews technical books for Packt, Manning, BPB and O’Reilly, staying at the forefront of best practices and often spotting subtle operational pitfalls authors miss. Based in Utrecht, he blends contractor flexibility with a long track record in mission-critical services (water management, fintech, utilities) and a preference for simplifying complex infrastructure rather than supporting Windows stacks. Outside work he’s a tech enthusiast who reads self-improvement books and follows SpaceX and DC Comics—proof he pairs curiosity with disciplined engineering.
