Supratik Chowdhury engineered and maintained data pipeline and workflow automation solutions for the ministryofjustice/analytical-platform-airflow repository over six months. He delivered production-grade ETL workflows, enhanced CI/CD automation, and improved reporting cadence by leveraging Apache Airflow, Python, and Terraform. His work included building robust scheduling controls, integrating CloudWatch logging, and optimizing resource allocation for daily and hourly data extraction tasks. Supratik also managed environment configuration, IAM permissions, and notification systems to ensure secure, reliable deployments. His contributions addressed both feature delivery and operational reliability, demonstrating depth in cloud infrastructure, workflow orchestration, and data engineering within a complex, evolving platform.
February 2026 monthly review for ministryofjustice analytical-platform teams. Delivered major feature work around WF02 reporting, CloudWatch log integration upgrades, and remuneration scheduling, complemented by DAG cleanup and Terraform-based data-processing work. The output is more reliable, scalable, and observable; daily reporting cadence is now strengthened, remuneration reporting runs hourly with improved retry logic, and stale/deprecated DAGs have been removed. Overall, the month advanced core business requirements for timely, accurate reporting and robust data processing.
