DevSecOps Specialist at South Florida Water Management District who modernized WAF protection, identity systems, and monitoring.
United StatesWhat I'm looking for
At South Florida Water Management District, I led a migration from Citrix NetScaler to FortiWeb WAF, designing security policies and application-layer protections. I also built API security policies for CORS and rate limiting.
I modernized authentication by directing an OAuth2 migration and leading an Active Directory migration to a centralized Identity Provider. I deployed Prometheus and Grafana monitoring with automated alerting, and automated system configuration and security patching with Ansible.
Previously, I investigated SIEM alerts with Mandiant FireEye and Splunk at UKG, and configured SSO/LDAP authentication for core banking applications at One Florida Bank. I’m seeking a Platform Engineering, SRE, or Security Engineering team where I can bring hands-on automation and security engineering expertise.
