January 2026 monthly summary for guardian/recipes-backend: Focused on delivering personalization capabilities, stabilizing data paths, and improving observability and client compatibility. Implemented end-to-end per-user data retrieval via the personalised endpoint, including authtoken and userid propagation and production URL adaptation, with testing support using a hardcoded endpoint. Added robust edge-case handling for missing personalization data (return undefined when data not found), and enforced safer caching through a Vary header and no-store in test mode to prevent cross-user leakage. Aligned the curation feed structure to client expectations and refined tests, logs, and code quality. Introduced metrics management with policies to improve observability and governance. This work enhances personalized user experience, reliability, and performance while providing clearer diagnosis signals for future improvements.

December 2025 (guardian/recipes-backend) delivered a container-based overhaul for Personalised Fronts, migrating from Lambda to CDK-managed containers. This enables cross-account access for Airflow and other services, and provides a cohesive front-end experience via a new personalised container fetcher and API surface. As part of the migration, Lambda-specific code and YAML references were removed, account IDs corrected, and container item references added to strengthen deployment reliability. Fronts were integrated with the new container fetcher, and end-to-end tests were updated to reflect the architecture change, including URL/endpoint corrections to reduce flaky behavior. Overall, the migration reduces maintenance complexity, increases scalability and security, and enables tighter integration with data pipelines and front-end workflows. Technologies demonstrated include AWS CDK, containerization, cross-account IAM/config, API design, and front-end integration, with strong testing and DevOps discipline.

November 2025: Delivered a targeted personalization pipeline and strengthened cross-account operations for guardian/recipes-backend. Highlights include the introduction of a Lambda-based Personalized Fronts Fetcher and a CDK-based front personalization construct with required IAM roles, CloudWatch alarms, and S3-based result storage, enabling centralized configuration and robust operations. Implemented secure Cross-account Airflow access with new IAM roles and policies across accounts. Also completed code quality improvements with lint fixes and suppressed test lint noise to reduce debt. Fixed IGA sponsorship leakage with case-insensitive sponsorship checks and safeguards, ensuring sponsorship is applied only to IGA-tagged items.
