System Administration

• 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.
• Built the operator back‑office — around 40 admin routes and 128 components covering claims, moderation, feature flags, cache and diagnostics — so the platform can be run without database access.
• 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.

This work is part of what we offer as System Administration, Platform & Solution Architecture, Cloud Infrastructure & Migration, DevOps & CI/CD Automation, Infrastructure as Code, Site Reliability & Monitoring, Website Development & CMS and Frontend Development.
