Over a two-month period, contributed to the govuk-one-login/txma-infra and govuk-one-login/data-analytics-platform repositories by delivering two key features focused on infrastructure and observability. Developed a robust CLI and configuration framework using TypeScript and YAML, introducing FiggyPudding-based configuration and improved stream management to enhance maintainability and future extensibility. Later, implemented comprehensive monitoring for the TXMA data pipeline and Event Consumer Lambda, leveraging AWS CloudWatch alarms and metric filters to capture errors and performance metrics across Glue, Athena, and S3. This work emphasized Infrastructure as Code, error handling, and proactive alerting, supporting reliability and operational visibility for critical data workflows.
