Antonio Gómez Castilla
Freelance Cloud Engineer & SysAdmin
I design, run, and stabilize cloud and on‑prem infrastructure. Fewer fire drills. More systems you can actually understand.

Services
What I can help with
Short-term or ongoing support for teams that need senior hands in cloud, systems, and production operations.
-
Cloud & AWS
Architecture, accounts, networking, cost, and deployments on AWS and hybrid environments. Infrastructure as code when it pays off.
-
Linux & SysAdmin
Servers, hardening, backups, performance, and the day-to-day that keeps production standing.
-
CI/CD & observability
Pipelines, repeatable deployments, metrics, logs, and alerts that fire on time — not after the fact.
-
Ops & reliability
Runbooks, automation, incident response, and operational security reviews.
Approach
How I work
Clarity before complexity. Automate the boring parts. Leave infrastructure documented and operable — not a maze only one person understands.
