What I'm looking for

I seek roles focusing on AppSec, cloud and network security where I can build DevSecOps pipelines, lead threat detection and incident response, and contribute to HIPAA/HITRUST-compliant security programs while growing technically and driving measurable risk reduction.

I am a cybersecurity engineer with 4+ years of hands-on experience across network security, SOC operations, and cloud security engineering.

I design and implement AppSec pipelines, embed SAST/DAST into CI/CD for PHI-sensitive applications, and modernize identity with OAuth 2.0/OpenID Connect to protect millions of accounts.

I have led threat modeling, firewall hardening, and segmentation efforts that reduced exploitable vulnerabilities by 46% and east–west exposure by 70%, while resolving 100+ critical CVEs and improving incident response times.

I align security engineering with HIPAA, HITRUST, NIST, and ISO standards, automate compliance and remediation with Ansible and SOAR, and continuously hunt threats to safeguard business-critical systems and data.
