PROFILE
Marco A.
Over ten months, contributed to the zitadel/zitadel repository by building and enhancing core authentication, authorization, and management APIs, focusing on secure, scalable backend systems. Delivered features such as relational table-backed organization and instance APIs, advanced session validation with TOTP and passkey support, and resource-based application management. Applied Go, SQL, and Protocol Buffers to implement robust data models, gRPC endpoints, and automated tests, while refactoring legacy logic for maintainability. Improved localization, security posture, and developer experience through internationalization, permission enforcement, and documentation updates. Addressed critical bugs, streamlined build tooling, and standardized terminology, demonstrating depth in backend development and system design.

Jan 1, 2026January 2026 monthly summary for zitadel/zitadel: Delivered a comprehensive naming standardization for the Management Console across the codebase, documentation, translations, and protobuf descriptions, reducing ambiguity and improving maintainability. The refactor aligns terminology (Customer Portal, Console, Admin Console) and sets a solid foundation for future translations and onboarding. It also partially closes issue #11279 and ties to #11390 (naming inconsistency cleanup).

Oct 1, 2025October 2025: Delivered foundational relational data capabilities and migration-ready API improvements for Zitadel. Implemented relational table-backed Organization APIs with full CRUD and domain associations, followed by parallel implementation for Instance APIs, establishing consistent data models and workflow automation across resources. Introduced a compatibility bridge to migrate from v2beta to v2 and refactored tooling to support this transition. Enhanced SQL with ignore-case operations to improve search flexibility and user experience. Strengthened quality through unit tests with DB mocking, added query option utilities, and established a reusable BaseCommand for future work.

Sep 1, 2025September 2025 monthly summary for zitadel/zitadel: Delivered three focused improvements that enhance data querying, platform flexibility, and SAML compliance. Key features and fixes: 1) User Metadata Filtering in v2 API: Adds ability to filter users by metadata key/value via the ListUsersRequest with SQL indexing and updated queries (commit 8df402fb4f2c984581a06e23bb5515f926991717). 2) EnableRelationalTables Feature Flag: Introduces a system-wide flag to toggle between relational tables and event sourcing, persisted in system and instance configurations and exposed via gRPC (commit 75a67be669a8daa5cc8af13fcb9049de492472dc). 3) SAML Attribute Order Compliance Patch: Updates SAML library to v0.3.6 to partially fix non-compliant attribute ordering; go.mod/go.sum updated (commit 8cc79c1376a24749fa947441e0fbec526f44a04a). Overall impact: improved targeted user data querying, safer architectural experimentation with data models, and enhanced SAML compliance. Business value: enables precise user segmentation, flexible data modeling, and reduced risk of SAML attribute-order issues. Technologies demonstrated: Go services, SQL indexing, gRPC integration, feature flag architecture, and module management.
