Mark Westerweel — Platform & DevOps consultant.

I build and fix infrastructure for Dutch organizations that take sovereignty seriously. Kubernetes, Proxmox, ArgoCD, ISO 27001. Open source where possible, own hardware where necessary.

Notes here, RCAs, and pieces on work I’ve put real time into. No hot takes, no AI content marketing, no LinkedIn cross-posts.

Five config lines against supply-chain attacks (npm + PyPI)

npm yanks malicious versions within 24-48 hours; PyPI quarantines new uploads within hours. A seven-day cooldown — five config lines — turns that window into your defence.

Claude Code from your phone — how I built it

An LXC, Tailscale, tmux, and an SSH key per device. Persistent, multi-device, nothing in a black box.
