Worked on enhancing the neynarxyz/OAS repository by updating OpenAPI specifications to better support payments and billing data. Focused on API development using YAML and the OpenAPI Specification, the work introduced a paymentMethod object and billingEmail field to relevant response schemas, improving the API’s ability to handle payment workflows. Automated synchronization of OpenAPI specs from the monorepo using GitHub Actions ensured consistency across environments and reduced manual overhead. These changes aligned CI/CD processes, minimized drift between repositories, and enabled faster downstream integrations, ultimately streamlining the integration of billing providers and improving the predictability of data contracts for payment systems.
