Worked on maintaining and improving the RecruitCRM integration within the NangoHQ/nango repository, focusing on backend configuration and API integration using YAML. Addressed a compatibility issue by updating the RecruitCRM provider’s base URL from .com to .io and correcting the candidates search endpoint to align with the latest API documentation. This update ensured that existing integrations continued to function without disruption, reducing the risk of outages for customers. The changes were validated through local and continuous integration testing to minimize regression risk. The work demonstrated careful attention to evolving third-party APIs and a methodical approach to backend maintenance and reliability.
