Over 14 months, Sean McMurtry engineered robust notification, reporting, and subscription features across the cds-snc/notification-admin and notification-api repositories. He delivered scalable, localized newsletter and reporting systems, modernized authentication with 2FA and security key support, and introduced billable SMS units for accurate usage tracking. Sean’s technical approach combined Python, SQLAlchemy, and JavaScript to implement asynchronous workflows, S3-backed storage, and feature flag governance, ensuring safe rollouts and operational resilience. His work emphasized accessibility, localization, and infrastructure stability, with thorough test coverage and CI/CD integration. The resulting systems improved reliability, developer productivity, and business value through maintainable, production-ready solutions.
February 2026 delivered measurable business value through scalable SMS billing, improved usage tracking, robust content handling, and infrastructure stabilization. Across three repositories, I delivered feature work for billable SMS units, refined admin usage calculations, fixed a content truncation bug preserving markup, and released infra version 2.27.1. The work included API and config changes, test coverage, and cross-team collaboration to improve cost visibility, accuracy of reporting, content safety, and deployment reliability.
