Madalina Baranga developed and delivered a new JSON schema for Worldline TAPI v1, integrating it into the extenda/hiiretail-json-schema-registry to support validated and versioned data exchange within the HiIconnect ecosystem. She focused on schema definition using JSON, ensuring robust governance and traceability from ticket to code through explicit commit references. Her work established a foundation for future schema evolution, enabling safer changes and improved downstream service integration. Although the scope was limited to a single feature over one month, the implementation addressed schema validation needs and enhanced the registry’s ability to manage evolving integration requirements for Worldline TAPI.
