Worked on the segmentio/action-destinations repository to deliver project-level event tracking support for user mappings, introducing an optional project_name field to enhance analytics accuracy and enable MoEngage integration. The implementation involved updating the user mappings UI, adding null checks for payload properties, and aligning MoEngage field mappings to the new project context. Expanded and updated tests ensured coverage for the new field and various payload scenarios, reducing regression risk and improving reliability. Leveraged TypeScript and full stack development skills, with a focus on robust testing practices, to streamline analytics workflows and reduce payload errors in project-specific data flows.
