Head of Security Engineering @Crexi

Los Angeles, CA, US

I lead full-stack cybersecurity and governance, risk, and compliance (GRC) programs across both corporate and product environments, aligning security architecture, engineering, and operations with SOC 2, ISO 27001, NIST 800-53, and privacy frameworks. Designed and implemented end-to-end security controls across cloud infrastructure, SaaS platforms, and internally developed products, embedding security into the SSDLC through, secure design reviews, and automated policy enforcement. Architected Zero Trust and Defense-in-Depth security models spanning identity, network, endpoint, application, and data layers. Directed enterprise identity and access management and encryption strategies across customer-facing and internal systems. Operationalized risk management through continuous control monitoring, automation and vendor risk assessments. Drove agentic, AI-powered security automation across detection, response, compliance evidence collection, and vulnerability management, significantly reducing mean time to detect (MTTD), mean time to respond (MTTR), and audit overhead while elevating overall security maturity.Implemented and operationalized core security platforms including a centralized SOC with SIEM-based detection and response, enterprise corporate VPN, and web application firewall (WAF) protections, integrating telemetry across cloud, SaaS, identity, endpoint, and application layers to enable continuous monitoring, threat detection, and policy enforcement at scale: Elevated overall security posture and compliance maturity by hardening and automating core security controls with agentic AI, reducing organizational risk exposure by ~70% while driving multi-million-dollar cost avoidance through security automation, vendor consolidation, and efficiency across corporate and product environments.
