Freelancer profile translated to English.

Description

I build and operate infrastructure platforms that scale.

With over 20 years in critical Linux environments and an automation-first approach, I help engineering teams focus on the product rather than their infrastructure.

What I bring:

→ Platform engineering & Kubernetes (CKA) — cluster ops, GitOps/ArgoCD, multi-tenant environments, OpenShift

→ Infrastructure automation at scale — Ansible AAP, 1,500+ managed nodes, zero-touch patching

→ Internal developer tooling — Python/Django, custom deployment and patching platforms

→ Observability & SRE — ELK Stack, monitoring, on-call, incident response

→ CI/CD — GitLab CI, ArgoCD, infrastructure pipelines

Scale references:

· Automated patching system covering 1,500 servers (NRB)

· Migration of 1,000+ managed hosts to new auth infra + Satellite

· Standalone Docker migration → OpenShift

I am looking for platform engineering roles in tech startups, cloud-native MSPs, or scale-ups with ambitious infrastructures. Remote-first, open to Belgium and Europe.

Certifications: CKA (2025) · RHCE · LPIC-2 · ITIL v4
