Engineering Director · ex-Bloomberg · PhD in CS (USC)
I work on identity & access management and cloud security & architecture — how people, workloads, and now AI agents authenticate, get authorized, and act safely at scale. Previously Tech Lead of Bloomberg's Authentication Platform (workforce + customer SSO); PhD in software architecture (recovery, decay, mining software repositories). 🏆 Best Paper, ICSA 2018.
- 🔭 Leading engineering @ Vinsmart Future — IAM / identity platform
- 🔐 Depth in: authentication, OAuth/OIDC & SSO, Zero Trust, workload & non-human identity
- ☁️ Focus: cloud-native security architecture, least-privilege & policy-as-code
- 🤖 Interest: identity for the AI-agent era — delegation, scoping, and safe autonomy
