Sai Dasari developed a production-grade CloudWatch-to-Athena data extraction pipeline for the ministryofjustice/analytical-platform-airflow repository, focusing on robust workflow orchestration and automation. Leveraging Airflow, AWS S3, and YAML configuration, Sai established environment variables, IAM permissions, and notification mechanisms to ensure secure and reliable data movement. The work included defining precise task dependencies for correct execution order, optimizing resource allocation to improve throughput, and enabling analytics workflows by granting access to Athena query results. Sai also enhanced maintainability by aligning release tags and cleaning up configuration files, demonstrating a thorough approach to both engineering depth and operational stability.
February 2026 monthly summary for the analytics platform (ministryofjustice/analytical-platform-airflow). Delivered a production-grade CloudWatch-to-Athena data extraction DAG and pipeline orchestration, establishing environment variables, IAM permissions, and notifications; ensured data write paths to S3 and defined task dependencies for correct execution order; removed retries to improve determinism and optimized resource allocation for better throughput. Implemented Athena query results bucket access to support analytics workflows and increased compute resources to scale ingestion. Completed repo/config hygiene with release tag alignment and minor cleanups.
