Building secure systems at scale

About Me

I'm a Security Engineer with a computer science background focused on platform and application security that scales. I build shared controls, automation, and cloud security, keeping things secure without slowing teams down. My earlier work in detection and incident response still shapes how I think about risk and how systems fail in practice.

I've scaled security through hypergrowth, from early-stage teams to thousands of employees. I serve on a technical advisory board and speak at conferences on practical, low-friction security. Outside work, I'm usually optimizing something, whether it's tools, workflows, or travel plans.

Featured Projects

Zero Trust Access Platform

Architected a company-wide zero-trust access model using audit log analysis to eliminate over-privileged accounts. Built automated RBAC workflows with least-privilege enforcement and temporary access patterns, reducing access requests by 80% while strengthening security posture across the organization.

Zero Trust IAM Python Security Architecture

Just-in-Time Cloud Access Management

Built a self-service AWS access platform allowing employees to request permissions directly from Slack. Access is automatically provisioned based on roles and risk level, fully temporary, logged, and secured with MFA and biometrics, simplifying IAM management while reducing security risk.

AWS IAM Python Zero Trust

Automated Software Governance

Built an AI-driven classification system to automatically detect and assess Chrome extensions and installed software. Using an allowlist approach based on categories and risk levels, the system integrates threat intelligence feeds to identify high-risk tools, eliminating manual review while improving security visibility.
