20 years building infra.
7M+ users to show for it.
CTO at Ualá México. Started in pentesting, moved to DevOps, joined Ualá on day one, and scaled it from a 6-month sprint to a multi-country fintech. Lately deep into AI and agents. Also: proud dad of Nina, an 11-year-old chocolate lab. 🐾
About
A bit about me
Experience
Where I've shipped things
Designing, building, and scaling infrastructure solutions for enterprise clients like Scripps Networks, Southwest Airlines, and WPP. Built monitoring systems, troubleshot production issues, and brought an infosec lens to every infrastructure decision — a combo that was rare at the time and turned out to be exactly what a fintech startup needed in 2016.
First time owning a security program rather than just executing on it. Covered the full spectrum — pentesting, server hardening, IDS and firewall deployment, and ongoing audits across servers and workstations. The role where defensive and offensive security clicked together as two sides of the same problem.
SAP security research for the AySA project, IT auditing for Warner Music, and development of security standards and checklists. First exposure to how large organisations think about (and budget for) security.
Where it all started. Network, web app, and wireless penetration testing. Security standards & checklists, hardening of critical systems, vulnerability management, firewall implementation. The kind of work that teaches you how things actually break — invaluable for building things that don't.
