Security-minded infrastructure engineer with a decade in the trenches.

I'm an IT and cybersecurity professional with 10+ years of hands-on experience running the systems organizations depend on every day: perimeter security, enterprise networks, virtualization, databases and cloud.

My career started on the service desk and grew into designing and operating infrastructure for more than 1,200 users across dozens of sites, leading migrations to Microsoft Azure, and managing a distributed engineering team as a player-coach — still hands-on, still on the keyboard.

What I bring to a team or a client:

  • Security that is operated, not just documented — firewalls, WAF, VPN, SSO and monitoring that cut security incidents by more than 70%.
  • Reliability as a habit — 99.9x% uptime targets met across networks, data centers and cloud workloads.
  • Clear communication — fully bilingual (English C2 / Spanish native), comfortable with executives, auditors and engineers alike.

This site is also my lab notebook: every project in the portfolio is reproducible, with write-ups, code and downloadable source.
