Experience

1. Software Engineering Manager

   Amazon Web Services (AWS)

   Jan 2021 — Present · Arlington, VA, US

   Shaped the technical strategy for AI and service-to-service security, creating centralized OAuth-based authorization services with OBO support for agents, standardizing patterns across teams, and reducing risky, fragmented implementations- Implemented a multi-phase agent authorization approach: established clear identity via OBO tokens, enforced delegated permissions, and ensured human-in-the-loop approval for sensitive actions, reducing potential security violations- Directed cross-team initiatives to eliminate class-wide confused-deputy risks using ABAC-based internal foundation services, ensuring all agent actions could be traced to originating humans- Delivered fine-grained authorization capabilities (ABAC, FGAC, step-up authentication) at scale, reducing unauthorized access incidents by 30%+ without impacting developer velocity- Scaled a Tier-1 internal authorization data plane from 3 → 42+ regions, cutting region launch time from ~90 days to under 2 weeks through automation and zero-touch deployments while securing core internal infrastructure- Retired a 10-year legacy authorization service, partnering with 500+ teams to consolidate tooling and achieve $5M+ in infrastructure and operational savings- Built observability, incident-response, and resilience mechanisms for Tier-1 authorization services, improving MTTR by 40–50%, shortening new-engineer onboarding from months to weeks, and aligning leadership on accepted, mitigated, and residual operational risk- Applied AI-assisted automation in security operations, reducing customer-facing MTTR from ~30 days to under 10 days while maintaining compliance and human oversight- Led and developed a multi-disciplinary org of 15+ engineers and managers, promoted multiple leaders, and served as an Amazon Bar Raiser with 300+ interviews conducted.
