Stability-first system administration for growing organizations
I'm a freelance system administrator and site reliability engineer based in Amsterdam, with more than 30 years of experience keeping IT reliable and maintainable.
I work with small and medium-sized organizations on system administration, device and identity management, and on-premise and cloud infrastructure, ensuring their IT stays stable as they grow.
I specialize in Apple and Linux-based environments, focusing on macOS, iOS, and Ubuntu.

Pragmatic approach
Deliberate execution, controlled change, and defined responsibility, focused on continuity rather than disruption.
- Short intake: what needs to be more stable tomorrow?
- Lightweight assessment: systems, access, devices, risks, dependencies.
- Quick wins first: then structural improvements with clear trade-offs.
- Handover: documentation and a setup that does not depend on me long-term.
Why work with me
- Experience: 30+ years in system administration and infrastructure management.
- Continuity: stability, observability, and recoverability as defaults.
- Communication: written plans, clear priorities, and fast feedback loops.
A typical first step is a short assessment, resulting in a concise and actionable plan.
