PROFILE

Ryan

Worked on the DEFRA/trade-exportscore-plp repository, delivering features and fixes focused on data parsing, validation, and regulatory compliance for packing list processing. Enhanced the CDS Model 2 parser and introduced a new Gousto model, implementing robust validation for establishment numbers, headers, and country of origin using JavaScript and Node.js. Improved data quality by refining regex-based parsing, updating prohibited item lists, and aligning eligibility checks with current regulations. Maintained clear versioning and release hygiene, deprecating legacy formats to ensure backward compatibility. Emphasized test-driven development and comprehensive unit testing, resulting in more reliable supplier data ingestion and streamlined compliance workflows.

December 2025 monthly summary focusing on key business outcomes and technical delivery across the DEFRA/trade-exportscore-plp repo. Delivered a robust Gousto Packing Lists Model with validation for establishment numbers and header formats, plus parsing logic for diverse packing list structures and comprehensive unit tests, enabling reliable supplier data ingestion. Improved data parsing reliability with Regex and validation refinements for blanket NIRMS, establishment numbers, and country of origin, supported by updated tests. Fixed data quality gaps in B&M data with totals-row validation, keyword-based row identification, and enforced field rules. Deprecated legacy Tesco Model 1 and ASDA Model 2 matchers/parsers to prevent deprecated formats, ensuring clearer backward-compatibility signals. Updated release versions to 6.28.3 and 6.29.2 to reflect the changes. Expected business impact includes higher data accuracy, reduced manual validation, faster downstream processing, and clearer versioning signals for integrations.
