SYSTEM STATUS: AVAILABLE FOR ENGAGEMENTS

I keep complex systems running — and build the ones that need to.

I'm Nick Hooijenga, a senior DevOps and infrastructure engineer based in Almere. For 16 years I've designed, built and operated the systems behind real-time platforms and enterprise services — from bare-metal datacenters to the workloads running on Kubernetes and OpenShift — and made sure they stay up.

What I do on the daily

Enterprises bring me in to run and modernise platforms that can't afford downtime. SMEs bring me in because I can own IT end-to-end — infrastructure, software and compliance — without needing a team around me to do it.

01 · Platform engineering

DevOps & Kubernetes

I keep Kubernetes and OpenShift workloads running inside a 3,000+ person organisation's existing platform — writing custom Helm charts, deploying through ArgoCD, and troubleshooting pods until they behave. I write my own Dockerfiles and work daily with Artifactory, CI/CD pipelines and GitOps, without needing to own the platform underneath to get real work done on it.

02 · Systems & networks

Infrastructure architecture

From datacenter to hybrid cloud: routing (BGP), firewalls, storage (SAN, ZFS, CephFS) and virtualisation, designed for 24/7 real-time services. I've replaced enterprise SAN and blade hardware with leaner, self-built alternatives without losing a night's sleep.

03 · Software

Development & automation

I write the software that removes vendor lock-in and manual work — from a custom IVR platform that replaced a €40k/year licence with an in-house one, to Infrastructure-as-Code that turns server builds into a repeatable script.

04 · Governance

Compliance & process

I've designed KYC frameworks and GDPR (AVG) processes alongside legal and banking partners, and turned audit findings into operational fixes. Most infrastructure engineers stop at uptime — I also make sure it holds up to scrutiny.

Where I've put this to work

A quick log of recent roles — the full history, including 90 SME clients under my own company, is on request.

2026 — now
Senior OPS Engineer
Government organisation, public sector (contract)
Keeping software running in production across two teams at a 3,000+ employee public organisation with strict compliance and four-eyes requirements. Configured RBAC roles in Active Directory and set up Linux servers, while working within the organisation's existing OpenShift 4 platform — writing custom Helm charts, deploying through ArgoCD, and keeping workloads and Artifactory artifacts in sync. Led a major version migration of a business-critical modelling platform and helped launch an internal digital-transformation initiative.
2016 — 2025
Senior DevOps Engineer & Technical Architect
Private company, real-time communications sector
Full ICT ownership for a 24/7 real-time communications company — infrastructure, governance and process automation, end to end. Designed a hybrid AWS architecture, replaced legacy SAN and blade servers with self-built alternatives, and built an in-house IVR platform that removed the last vendor lock-in and cut licence costs from €40,000/year to zero. Also owned the company's KYC and AVG compliance frameworks.
2010 — 2016
Owner
Hooijenga IT
Ran IT for 90 SME clients across very different sectors — dental practices, estate agents, painters, taxi companies and more — covering webhosting, cloud email and general systems management.
// about

Tailored to your use case, not a template

I like systems that are complex enough to be interesting and I take pride in making them boring to operate — reliable, monitored and well-documented, so nobody has to think about them at 3am. That instinct comes from 16 years of being the person who gets the call when something breaks.

I work directly with you, not through a layer of account managers. Whether that means joining an existing team on a Kubernetes platform, or being the entire IT department for a smaller company, I bring the same standard: build it properly, document it, and make sure it still works when I'm not in the room.
