In October 2025, Ian McLaughlin developed a dedicated SIC codes mapper for the companieshouse/confirmation-statement-api repository, focusing on robust data mapping and transformation. Leveraging Java and Spring, Ian integrated a component that enables seamless JSON to DAO conversions and supports list transformations for SIC codes. The mapper also enriches the DAO with section status based on code presence, addressing data consistency requirements. Ian standardized Spring as the default component model and consolidated dependency management within the project’s pom file. The work, delivered across three traceable commits, demonstrated depth in Spring integration, data mapping, and unit testing, ensuring maintainable and reliable enhancements.
