Ryan McLean developed and maintained the govuk-one-login/authentication-api, delivering a robust serverless authentication and account management platform over six months. He engineered features such as multi-factor authentication, bulk user management, and secure API Gateway integrations using AWS Lambda, CloudFormation, and IAM policy management. Ryan implemented Infrastructure as Code for repeatable deployments, strengthened security through policy hardening, and introduced CI/CD pipelines with GitHub Actions. He also enhanced operational visibility with CloudWatch and SQS-based monitoring. His work included Python scripting and YAML configuration, resulting in a scalable, auditable backend that improved deployment reliability, security compliance, and streamlined user lifecycle management.

Month: 2025-12 | Repository: govuk-one-login/authentication-api. Key outcomes: two security and clarity features completed. 1) API Gateway Authorizer Role Security Hardening: tightened permissions management and control for delegated permissions to reduce permissions errors. Commits included: a3767716e54b4520708c0e8744368b1eb405a4fc (BAU: Remove role to avoid permissions error) and db81c9fdc84ad69403f3f09cad9d1997d6617d31 (BAU Add Perm Boundry to AuthRole). 2) Codebase naming clarity for OTP notification: renamed account-management-send-otp-notification to send-otp-notification to improve clarity and consistency. Commit: d3c4ebb520dafbbbcb46d8dbaddcdd52648afc4a. No major bugs fixed this month. Impact: improved security posture, reduced risk of misconfiguration, and clearer, more maintainable code paths for OTP notifications. Technologies/skills demonstrated: AWS API Gateway, IAM permissions design, secure role management, code refactoring, naming convention enforcement, and Git-based change management.

Month: 2025-10 — Delivered a consolidated serverless authentication and account management platform with MFA, OTP, Lambda-based user updates, account deletion, and API gateway integration. Migrated core auth components and updated API schema inline (openapi_v2.yaml); completed Authorizer API migration to improve security and reliability. Strengthened security and access control for account management via IAM policy migrations, KMS key access, and policy updates for functional equivalence, including adding matching policies. Implemented end-to-end monitoring and notifications through SQS-based handlers and CloudWatch alarms, with SNS & CloudWatch migration for unified observability. These changes deliver improved security posture, streamlined user lifecycle flows, reduced operational risk, and a scalable serverless foundation for future features.
