PROFILE
Carles Andrés
Carlos Andres contributed to the DEFRA/epr-backend repository over six months, focusing on secure authentication, robust API development, and architecture governance. He implemented end-to-end Defra Id authentication with JWT and OIDC, enhanced user role management, and introduced detailed logging for improved traceability and compliance. Using JavaScript, Node.js, and MongoDB, Carlos delivered new APIs for organization management, strengthened error handling, and resolved data integrity issues during seeding. He established architecture decision records to standardize frontend and backend structures, improving maintainability and onboarding. His work demonstrated depth in backend development, security best practices, and technical documentation, resulting in a more reliable platform.

Jan 1, 2026January 2026 – DEFRA/epr-backend: Focused on data integrity and security observability. Resolved MongoDB unique index conflicts during seeding of approved registrations and accreditations and introduced functions to generate unique registration and accreditation numbers. Implemented an authentication failure logger to capture 401 errors, improving monitoring and security visibility. These changes reduce seed-time errors, enforce data constraints, and enable faster incident response.

Nov 1, 2025November 2025 (2025-11) focused on strengthening authentication foundations in DEFRA/epr-backend. Delivered testing scaffolding for Defra Id / OIDC authentication, including mock JWT-based authentication, OIDC server scaffolding, and deliberately crafted tokens (including invalid signatures) to validate error handling across authentication flows. Implemented Defra Id token validation with a configuration-driven authentication toggle to enable/disable Defra Id authentication with updated configuration. Fixed issues in the mock authentication tokens to ensure reliable test behavior. Together, these efforts reduce security risk, improve test coverage, and enable safer rollout of authentication features. Key tooling and skills demonstrated include: JWT/OIDC, mock servers, test scaffolding, feature flags, and deployment configuration changes.
