I strengthen cybersecurity, ISO 27001 compliance, and incident response across government and enterprise environments.
PeruWhat I'm looking for
I've strengthened information security programs at OSIPTEL, Pension 65-MIDIS, OEFA, Claro/Telmex, and The CCS Companies, with more than 25 years in IT and over 10 years focused on cybersecurity. At OSIPTEL, I managed digital security incidents, led a six-person team, and coordinated vulnerability remediation that achieved 100% compliance with antimalware and security patching KPIs in a pilot plan.
I'm experienced in ISO 27001 ISMS coordination, risk management, ethical-hacking assessments, security audits, infrastructure security, and awareness programs. I also bring hands-on experience with firewalls, Active Directory, VMware, Oracle, Windows, Linux, and security tools including Kali Linux, Metasploit, and Tenable.IO.
