Worked on the hmcts/ARIAMigration-Databrick repository to enhance data migration pipelines using Python, Azure Functions, and Azure Blob Storage. Focused on improving throughput and reliability by tuning batch sizes, implementing chunking, and introducing concurrency controls for asynchronous processing. Refactored the Appeals data pipeline to support both JSON and plain URL blob downloads, with robust error handling and resource cleanup. Addressed critical bugs by reverting storage account configurations and aligning secret management, ensuring stable credential handling. Maintained clear traceability through explicit commits, supporting maintainability and auditability. The work emphasized scalable, resilient cloud integration and end-to-end deployment reliability.

Dec 1, 2025December 2025 (hmcts/ARIAMigration-Databrick): Stabilized storage integration for the Azure Function used in data migration. Delivered a critical bug fix by reverting to the TT storage account and aligning container secrets retrieval with the reverted storage configuration. This ensured correct storage credentials and reliable function operation, reducing the risk of credential-related failures and outages in the migration workflow. Demonstrated hands-on capability with Azure Functions, storage account configuration, and secret management, with clear change traceability and impact on production reliability.

Nov 1, 2025November 2025 milestones for hmcts/ARIAMigration-Databrick focused on performance tuning of Azure Functions and robust data processing pipelines. Delivered initial throughput optimization via a concurrency limiter and smaller batch size to boost checkpointing speed and processing throughput (order-agnostic processing), with a rollback to preserve stability after testing. Refactored the Appeals data processing pipeline to download content from source blob URLs (supporting JSON payloads and plain URLs) and upload to target blob storage, enhancing error handling and resource cleanup. These efforts improved end-to-end data migration reliability, throughput, and maintainability, laying groundwork for scalable, resilient data integration.
