Worked on the beckn/beckn-onix repository to deliver offline schema validation and a more maintainable processing pipeline. Developed local schema validation preloading, allowing Go-based backend systems to cache and use schemas from a specified directory, which supports development and testing without network access. Refactored the reqMapper logic into a dedicated transformPayload step, improving payload transformation accuracy and integration with schema validation. Focused on API development and schema validation, the work included targeted test stabilization and safeguards to ensure reliability. These changes reduced network dependency, streamlined development workflows, and enhanced the separation of concerns within the backend processing pipeline.
