Anyone can claim to be senior. These you can inspect.
Choosing an engineer usually means taking someone's word for it. I would rather you looked at the work. Both of these are public and live.
A working reference environment for test labs and greenfield builds: Packer templates for Windows and Linux across Proxmox, VMware, AWS, Azure and GCP, Ansible roles for configuration and hardening, and a CI workflow that validates every template on push.
Inspect the commit history, not just the README — it shows how the work is actually done.
itsurgery.me — a live business site built with Eleventy: templated so 28 pages share one layout, contact details held in a single data file, WCAG 2.1 AA verified, machine-readable sitemap, forms handled without a backend, and continuous deployment on every push.
Small in scope, but a fair sample of standards: accessible, fast, maintainable, no server to patch.
If you need to see work closer to your own problem, ask. I can usually walk through an approach or build a small proof of concept — darren.pilkington@it-architect.uk.
