Developed and delivered a new JSON schema for the Omnium OMS Connector configuration within the extenda/hiiretail-json-schema-registry repository, focusing on robust schema design and configuration management. The work established detailed mappings for order statuses, tender types, and shipment methods, enabling streamlined onboarding and validation for OMS integrations. Leveraging skills in API integration and JSON, the schema introduced versioning to improve maintainability and traceability, while also aligning closely with ticketing for clear development tracking. This approach enhanced configuration validation and reuse across connectors, reducing both onboarding time and runtime errors, and supporting more reliable and scalable integration workflows for future development.
