Worked on the MewsSystems/gitbook-connector-api repository to deliver AssignmentTargetType support within the Routing Rules API, enabling explicit handling of company-to-bill relationships for more granular routing decisions. The implementation was additive and non-breaking, ensuring compatibility with existing integrations while expanding routing capabilities. Updated API documentation and changelog using Markdown to reflect the new property and corrected related links, improving developer guidance and reducing manual routing effort. Demonstrated skills in API documentation and technical writing, collaborating across product and documentation teams to enhance routing accuracy and streamline complex billing workflows for customers integrating with the GitBook connector API.
