What I'm looking for

I seek a mid-level cybersecurity role focused on vulnerability management, cloud/DLP/endpoint security, and AI-driven automation within a collaborative team that values measurable impact and professional growth.

I am a cybersecurity professional with 3+ years of hands-on experience securing cloud environments, endpoints, and enterprise infrastructure. I specialize in vulnerability management, DLP, patching, and hardening while driving measurable risk reduction.

I have led vulnerability programs and remediation efforts that cleared 400,000+ CVEs in three months, including mitigation of 10,000+ critical threats, and earned direct client recognition for results and client satisfaction.

My toolset includes Tenable/Nessus, Tenable.io, Symantec DLP/CloudSOC, AWS Macie, Palo Alto firewalls, and CrowdStrike Falcon, and I apply UEBA, shadow IT analysis, and digital forensics to strengthen security operations.

I hold a Master of Science in Cybersecurity and pursue AI-driven security development and automation; I build defensive projects such as honeypots, multi-cloud container deployments, blockchain-based backup systems, and CTF-style labs to advance practical security capabilities.
