- Built and maintained the user-facing analytics and administration portal, including API key management, user/role management, team invitations, and enterprise SSO/MFA configuration.
- Led migration of authentication from a custom-built system to Auth0, architecting multi-tenant support (users associated with multiple organizations), role-based access control (RBAC), and organization-level SSO/MFA.
- Migrated 10k+ users and organizations to the new auth system with zero downtime and no service disruption.
- Engineered resilience for third-party auth dependencies: implemented multi-layer caching, rate-limit failover, and circuit breakers to keep system available under load and during upstream outages.
- Introduced observability across backend services using Sentry, Prometheus, and Grafana, enabling real-time error tracking, metrics collection, and system health dashboards for faster incident detection and debugging.
