What I'm looking for

I’m looking to build and optimize enterprise threat detection and incident response with SIEM/SOAR, automate vulnerability and secure SDLC workflows, and own compliance outcomes in multi-cloud environments where measurable security improvements are valued.

I’m a Senior Cybersecurity Engineer with 11+ years of hands-on experience engineering enterprise-grade security systems, leading threat detection and incident response, and architecting compliance frameworks across complex multi-cloud environments. I bring deep expertise across the full security stack—SIEM/SOAR engineering, offensive/defensive operations, vulnerability lifecycle management, secure SDLC integration, and regulatory compliance (NIST 800-53, ISO 27001, SOC 2, HIPAA, GDPR, PCI-DSS).

I’ve driven measurable outcomes like 97% MTTR reduction, 70% fewer false positives, 60% fewer repeat vulnerabilities, and 100% CI/CD security coverage. I engineer high-fidelity SIEM pipelines, build SOAR playbooks that automate response workflows, run proactive threat hunting with YARA/Sigma/IOC feeds, and harden cloud and container environments (Docker/Kubernetes) using benchmark-aligned controls—while also delivering compliance audits and security documentation that improves audit readiness and onboarding.
