Lead platform engineer with 17+ years building scalable, high-performance infrastructure on AWS — the kind that goes from zero to millions of users and stays cheap and boring to run.
The part I enjoy most is what comes after the work is done: turning hard-won production experience into clean, reusable references other people can build on, and shipping small, well-made tools. Reusable AWS Organizations guardrails, an OpenTofu + EKS reference architecture, a self-hosted full-text RSS tool, a calendar utility on the App Store. Build it properly, document the sharp edges, give it away to the community.
You can find me as @mijndert most places, with a longer home at mijndertstuij.nl.
