@ryandonjamilosa

I investigate threats, build secure systems, and turn telemetry into actionable insights.

What I'm looking for

I'm looking to apply hands-on cybersecurity, incident investigation, secure networking, and data analytics skills in a role where I can keep learning and contribute to security operations.

I've built a PHP-based Asset Tracking System for DHSUD–RO5 with role-based access control, RFC 5424 syslog audit logging, and JSON snapshots to support hardware lifecycle tracking and security accountability.

Through hands-on cybersecurity, cloud, and analytics projects, I investigate simulated endpoint attacks with Wazuh and Sysmon, analyze data in Google BigQuery, and implement secure WireGuard VPN connectivity between Linux firewalls and AWS environments.
