Developed and delivered a complete eBay integration for the NangoHQ/nango repository, enabling both production and sandbox environment configuration, API connections, and workflow execution. The work involved designing integration architecture, orchestrating API authentication and data synchronization, and managing environment-specific settings using YAML. Comprehensive documentation was created in Markdown to support onboarding and developer adoption, while SVG assets were produced for branding and template logos. This integration expanded Nango’s marketplace coverage, allowing users to connect to eBay for new transactions and streamlined workflows. The project demonstrated skills in API configuration, integration development, and technical documentation, with a focus on maintainability and usability.
