What I'm looking for

I seek roles where I can lead application and cloud security programs, improve remediation processes through automation, mentor teams, and drive measurable reductions in risk.

I am a Senior Security Specialist with 6+ years protecting enterprise infrastructure, OSCP-certified and focused on application security, red teaming, and cloud security. I have reduced security incidents by 40%, led application security programs for 500+ applications, and identified and remediated 100+ high-severity vulnerabilities.

I build practical security programs from scratch—introducing security champion initiatives, automating vulnerability triage, and integrating CI/CD testing to cut remediation times and MTTR dramatically. I collaborate closely with engineering and SOC teams to prevent breaches, mentor teammates, and deliver measurable improvements in security posture.
