October 2025: Delivered two key capabilities across core services with measurable business value. In nhs-notify-web-gateway, PDF Upload Support in Letter Templates enabled PDF uploads via create/edit endpoints by relaxing AWS WAF rules and adjusting SQLi handling, while maintaining protection with a dedicated multipart/form-data rule. In nhs-notify-iam-webauth, Frontend Build and Code Quality Enhancements improved build reliability and code quality through dependency updates, favicon configuration refactor, and tightened pre-commit/editorconfig tooling. Overall impact: safer, more capable template workflows and faster, more maintainable frontend builds. Technologies demonstrated: AWS WAF tuning, SQLi handling strategies, multipart/form-data processing, dependency management, pre-commit tooling, and editorconfig enforcement.

September 2025 highlights security hardening and safe-ops improvements across two NHSDigital services. Delivered two security-focused changes with traceable commits: AWS SDK update in nhs-notify-iam-webauth and WAF allowlist update for letter template uploads in nhs-notify-web-gateway. There were no major bug fixes in scope this month. These changes reduce security risk, improve deployment safety, and enhance reliability of core user workflows. Demonstrated skills in AWS security, firewall rule management, and change-tracking using CCM tickets.

August 2025 monthly summary for NHSDigital Notify repos focusing on security, reliability, and maintainability improvements across three services. Key features delivered: (1) CIS2 Authentication via JWKS in nhs-notify-iam-webauth — removed deprecated client secret authentication and migrated Terraform configurations and Lambda logic to exclusively use JWKS for authentication, strengthening security. (2) Web Application Firewall update in nhs-notify-web-gateway — enabled the 'create' action for large-payload template creation, with a backwards-compatible rule to ensure correct handling of new template creation requests. (3) CI/CD tooling and maintenance in nhs-notify-web-template-management — enhancements to pre-commit configuration and GitHub Actions to newer versions, plus routine dependency maintenance and AWS SDK upgrades to improve reliability, security, and test robustness. Overall, this month delivered stronger security controls, more robust deployment pipelines, and a cleaner, more maintainable codebase across the Notify platform.

July 2025 performance focused on establishing robust CI/CD and test reporting foundations across NHSDigital’s notification projects, delivering cross-repo standardization, improved reliability, and scalable workflows.

June 2025 monthly summary for NHSDigital development efforts across identity and template management services. Focused on security hardening, environment standardization, and RTL workflow improvements. Delivered features with clear business value: stronger authentication via JWKS, standardized costing with Cognito Essentials tier, and RTL-specific template handling to reduce manual validation overhead while preserving correctness.

May 2025: Delivered security, reliability, and efficiency improvements across identity and template management services. Implemented JWKS key rotation via AWS Lambda with automated KMS key lifecycle and public JWKS updates in S3, reducing exposure risk and improving rotation compliance. Optimized OAuth2 login polling to lower resource usage and enhance user experience. Released a data migration tool for user templates in DynamoDB with pre/post-backups to S3 and CLI configurability, enabling safer ownership transfers. Streamlined CI/CD by omitting dev dependencies during npm ci, cutting build footprint and accelerating feedback loops. Introduced automated test data cleanup and deterministic testing to maintain clean test environments and improve test reliability. These changes collectively improve security, performance, cost efficiency, and developer productivity.

April 2025 monthly summary: Delivered the Shared Sandbox KMS Key Provisioning feature for NHSDigital/nhs-notify-iam-webauth. Implemented a reusable Terraform module to provision an account-scoped KMS key with configurable account ID, component, environment, project, region, deletion window, and alias, exposing the ARN as an output for secure sandbox key management. No major bugs fixed this month; emphasis on secure, standardized sandbox access. Business impact: accelerates sandbox onboarding, reduces manual effort, and strengthens security governance with auditable key management. Technologies demonstrated: Terraform module design, parameterization, AWS KMS integration, Terraform outputs, and infrastructure-as-code best practices.

March 2025 performance summary: Delivered user-facing navigation reliability improvements and security-focused infrastructure enhancements across two NHSDigital Notify projects. Key wins include footer navigation correctness, tests refactor, and CI workflow updates; security tooling improvements with a secret scanner upgrade; a new public signing keys infrastructure module with IaC (S3, CloudFront, ACM, WAF) and domain uniqueness prep. These efforts improved navigation for policy/access pages, strengthened governance and security posture, and modernized CI/CD pipelines.

February 2025 focused on delivering user-centric UX improvements, stabilizing end-to-end tests, and enhancing infrastructure across NHS Notify repos. Highlights include removing backend confirmation emails on template submissions, CIS2 login test modernization, test infrastructure stabilization, CloudFront-based query-string forwarding, and CIS2 sign-in button UI/accessibility enhancements. Collectively these changes reduce user noise, increase test confidence, and accelerate release readiness, delivering measurable business value.

Month: 2025-01 Key deliverables focused on CIS2 authentication integration and routing security for the NHSDigital/nhs-notify-iam-webauth repository. Key features delivered: - CIS2 Login Flow Integration across frontend and infrastructure (environment variables, Terraform, Amplify outputs, OAuth state handling) to provide a streamlined authentication experience for the CIS2 provider.
