Becka Lelew engineered authentication and authorization features across the govuk-one-login/authentication-api and related repositories, focusing on secure, observable, and scalable user journeys. She delivered modular Lambda architectures, robust MFA reset flows, and end-to-end OIDC integrations, leveraging TypeScript, Java, and AWS services such as Lambda and DynamoDB. Her work included implementing JWT-based authorization, audit logging, and dynamic state management, while enhancing test reliability and observability through CloudWatch metrics and Dynatrace integration. Becka refactored APIs for maintainability, introduced infrastructure-as-code with Terraform and CloudFormation, and improved frontend UX with internationalization and analytics, demonstrating depth in backend integration and production-grade deployment strategies.

December 2024 (Month: 2024-12) delivered production-ready, observable, and user-centric improvements across authentication components, with a strong focus on business value, reliability, and scale. Key work includes production-grade TICF deployments, a modular TICF CRI Lambda architecture, secret management for Dynatrace integration, expanded observability dashboards, and UX improvements for authentication flows. The work improved deployment safety, performance readiness, and user experience while strengthening security and monitoring. Highlights include alias-based production deployment and build-time TICF integration for safer rollbacks; refactoring TICF CRI into a reusable endpoint-lambda module with environment parity and initial performance tuning; Dynatrace secret retrieval via Secrets Manager per environment; broad observability enhancements (shared dashboards, environment-specific dashboards, and improved metric labeling); and user-focused security code workflows with translations plus an MFA reset flow fix. This work demonstrates end-to-end delivery from backend Lambda architecture to frontend UX, with a cohesive emphasis on reducing production risk, increasing observability, and delivering measurable business value.
