A standardized OAuth2 authentication and authorization system rolled out across multiple client deployments of Opal's platform.
I led the design and implementation of the OAuth2-based authentication and authorization system, and drove its standardization across the multiple client deployments — this was a leadership-and-build role, not implementation-only: it required getting buy-in for a common security model across otherwise independent client environments.
Standardize on OAuth2 as the single authentication/authorization model across all client deployments.
Why — A common, well-understood standard reduces the security review burden per client and lets the platform team reason about access control once instead of per-deployment.
