February 2026 monthly summary for govuk-one-login/ipv-cri-f2f-front: Delivered user-facing functionality, stabilized deployments, and reduced maintenance burden. Key features and reliability improvements include a language selection feature for posted letters with English, Welsh, or both, plus routing, validation, browser tests, and a feature-flag to control visibility. Major bugs fixed and stability improvements encompassed stabilizing the CI/CD post-merge workflow, environment variable adjustments for browser tests, removal of 'continue on error' in tests, enhanced test logging, and ensuring runtime availability of the DynamoDB client by moving @aws-sdk/client-dynamodb from devDependencies to dependencies. Additional technical efforts included dependency minimization to reduce package bloat by cutting minimatch-related dependencies in the F2F project. Overall impact: Improved multi-language user journeys, faster and more reliable deployments, and a leaner, more maintainable codebase. Technologies/skills demonstrated: FE development with routing/validation, feature flagging, browser testing, CI/CD optimization, AWS SDK dependency management, and dependency hygiene.
