In September 2025, Chris Barber enhanced cross-language role-based access control in the workos/workos-node and workos/workos-python repositories. He implemented multi-role support for organization memberships, updating both Node.js and Python SDKs to handle arrays of roles in authentication flows and JWT decoding. This involved interface and serializer updates, as well as adjustments to session authentication and membership creation for more granular permissions. Chris managed dependency and version updates, ensuring release readiness and smoother onboarding. His work demonstrated depth in API development, authentication, and backend engineering, leveraging TypeScript and Python to improve enterprise governance and maintain robust, scalable authorization workflows.
