I am a Cloud Security Architect with an engineering-first approach to securing multi-account, multi-region AWS environments. I design and embed controls into foundational architectures to prevent drift and reduce attack surface rather than retrofitting security after deployment.

At AWS I built and operationalized CSPM solutions that delivered real-time visibility across 1,000+ accounts, improved compliance scores by up to 35%, and automated audit preparation to reduce manual effort by 60%. I led large cloud security engagements, closed 90% of high-severity findings in under 30 days, and deployed preventive SCPs and organizational CloudTrail to eliminate common misconfigurations.

I bring hands-on incident response and forensics experience, correlating identity, network, and workload telemetry to isolate threats quickly — including containing a breach and identifying root cause within eight hours. I also designed DDoS mitigation that reduced malicious traffic by 97%, preserved 99.99% uptime, and avoided significant SLA penalties.

I mentor engineers and deliver training content to scale secure operations: I co-authored workshops, built labs, trained 200+ engineers with top feedback scores, and coached junior staff to improve onboarding speed and customer satisfaction. I pursue continuous improvement through automation, Terraform IaC, CSPM integrations, and security-first DevOps practices.
