Worked on the govuk-one-login/ipv-cri-common-lambdas repository to enhance deployment reliability and enable seamless SIS integration. Delivered features such as configurable VPC stack naming and pipeline-safe parameterization, allowing non-CRI services to deploy without conflicts. Introduced an OAuth server for the Stored Identity Service with a toggle for VC issuance and configurable client IDs, supporting integration while maintaining backward compatibility. Improved infrastructure as code practices using AWS CloudFormation, AWS Lambda, and TypeScript, and optimized parameter management by conditionally skipping unnecessary SSM parameter creation. These changes reduced deployment failures, streamlined cross-stack integration, and promoted reusable OAuth code across multiple services.
Month: 2026-06 — Focused on enabling SIS integration and improving deployment reliability for the ipv-cri-common-lambdas. Key features delivered include: 1) VPC Stack Naming Configurability and Pipeline Compatibility: added configurable VPC stack name with default 'cri-vpc' and renamed VpcStackName to VpcStack to prevent None overrides, ensuring pipelines for non-CRI services (e.g., SIS OAuth server) deploy reliably. 2) OAuth Server for SIS with VC Issuance Toggle and Configurable Client IDs: introduced a flag to toggle VC issuance and configurable default client IDs; supports SIS integration without requiring core-infrastructure while preserving backward compatibility. 3) Avoid creating unnecessary SSM parameter for decryption key: conditionally skip SSM parameter creation when not needed by feature flags, eliminating reads of non-existent parameters. Benefits include reduced deployment failures, easier cross-stack integration, and reusable shared OAuth code.
