About me
I'm a US Army veteran with 14 years of corporate hands-on Linux & FreeBSD systems administration. I fix what's broken: crashed services, server security, botched PHP updates, broken migrations and I document everything I change so the problem stays fixed.
What I work with every day: RHEL, FreeBSD, Nginx, Docker, ZFS, pf, upgrades, WordPress, Laravel, hosting setup, hosting maintenance.
How I work: fast, in plain English or Spanish, never touching a system without a rollback plan. You get a root-cause report after every job, not just a "fixed it" message.
If I can't fix it, you don't pay.
