Cybersecurity Specialist
Cybersecurity specialist with 10+ years securing on-premises and cloud infrastructure across Latin America. I design resilient security architectures, lead threat intelligence and incident response, and embed security into the SDLC rather than bolting it on afterward — bringing both offensive and defensive expertise to every engagement.

Cybersecurity specialist with 10+ years securing on-premises and cloud infrastructure across Latin America. I design resilient security architectures, lead threat intelligence and incident response, and embed security into the SDLC rather than bolting it on afterward — bringing both offensive and defensive expertise to every engagement.
My background spans Active Directory hardening, email security, endpoint protection, and multi-cloud environments — work that's shaped a practical philosophy: build for resilience first, treat threat intelligence as a continuous input rather than a quarterly report, and measure success in risk reduced, not tickets closed.
