You have practical knowledge of RESTful APIs, authentication, web hooks, API testing tools, and JSON, XML, and CSV data formats; working SQL proficiency for investigation, validation, and monitoring; and basic client-side JavaScript and browser troubleshooting (link construction, URL encoding, redirects, and tags). You use logs, data, and technical evidence to identify root causes and tell apart partner implementation issues, configuration gaps, data problems, and product defects, and you translate your findings into clear partner guidance, internal documentation, or high-quality engineering escalations.
