PROFILE

Livio Spring

Over a two-month period, contributed to the zitadel/zitadel repository by delivering two security-focused features in Go, emphasizing backend and API development. The work began with hardening user self-management permissions, introducing stricter checks for verified email and phone updates, and expanding automated test coverage to ensure compliance and governance readiness. In the following month, consolidated access control for projects and resources by implementing resource owner checks and refining data retrieval permissions. Enhanced the authorization middleware with route prefix handling, strengthening security consistency across API endpoints. The approach demonstrated depth in context management, middleware design, and gRPC integration, addressing multi-tenant security needs.
