System Administration

Keeping the lights on

Day-to-day care of servers, mail, accounts and updates, so the things everybody relies on stay boring.

Selected work demonstrating this service.

Administered 40 websites on Ubuntu Linux hosting servers with Apache and Nginx, ensuring high availability and performance.
Planned and implemented new infrastructure functionality for internal and external systems, building solutions durable enough to still run years later with minimal change.
As one of the first hires, designed and built the entire core infrastructure and supporting processes from scratch for a green‑energy SaaS startup, laying the foundation for rapid growth.
Ran the whole company on one 512 MB single‑core host — a git forge, a web server serving seven domains, Tor, two alternate‑protocol servers, backups and intrusion banning — by treating 464 MB of usable memory as the binding architectural constraint.
Deployed the company's own git forge on Soft Serve, private by default with no web panel and its SSH port bound to loopback behind a jump host, and made the landing page in front of it a build artefact of the main site rather than a hand‑kept copy.
