Rachel Roberts engineered authentication, observability, and infrastructure features across the govuk-one-login platform, focusing on both backend and frontend systems. She delivered secure key discovery endpoints and automated key rotation in the ipv-cri-uk-passport-api, enhanced dashboard metrics and data visualization in observability-configuration, and improved reliability through structured logging, health monitoring, and dependency management. Using JavaScript, Node.js, and AWS CloudFormation, Rachel standardized CI/CD pipelines, upgraded Node.js runtimes, and implemented environment-specific alerting. Her work demonstrated depth in infrastructure as code, cryptography, and internationalization, resulting in resilient, maintainable services that improved user experience, operational insight, and compliance across multiple repositories and environments.
In March 2026, delivered significant improvements to the STS metrics dashboard in govuk-one-login/observability-configuration, enhancing accuracy, usability, and business insight for authentication metrics. Key outcomes include updating cluster version, metric renaming, and refined layouts that clearly represent Auth Code Exchange Rate, Session Creation Rate, code exchange rates, orchestration return rates, and lambda/transaction message codes. These changes improve data fidelity for decision-making and operator productivity.

Summary for 2025-08: Delivered three initiatives spanning testing enablement, alert orchestration, and cryptography correctness across three repositories. Key features delivered: (1) ipv-cri-common-lambdas: Fraud & DL APIs Development Environment Feature Flags for Testing enabling development mode for di-ipv-cri-fraud-api and disabling legacyFallbackKey in dev to simplify testing of key rotation and configurations. (2) ipv-cri-uk-passport-api: Centralized certificate expiry alert routing by redirecting expiry alarms to platform-alarm-critical-alert-topic across all environments for unified alert management. (3) ipv-cri-common-infrastructure: PublishKeyHandler bug fix addressing RSA-OAEP-256 algorithm name formatting by switching from underscores to hyphens, with tests updated accordingly. Major bugs fixed: correct algorithm name formatting to ensure cryptographic operations are executed with RSA-OAEP-256. Overall impact: faster, safer development cycles for fraud APIs; more reliable, centralized alerting reducing incident response time; and cryptographic correctness lowering runtime risk. Technologies/skills demonstrated: feature flag governance and environment-specific configurations; event-driven alert routing and centralized monitoring; cryptography correctness and test coverage; cross-repo collaboration and code quality. Business value: accelerated fraud feature validation, improved operational observability, and robust crypto operations across services.
