Worked on the AgoraDocSource repository to streamline and clarify API documentation by removing deprecated CDN streaming APIs and related references, reducing technical debt and simplifying the codebase. Focused on API design and technical writing using XML, the work included updating documentation to align with current streaming architecture and deprecation policies. Delivered features such as the removal of uplink and downlink multipath modes and added guidance for Video Encoder Configuration timing to improve first-frame latency. These changes enhanced developer onboarding, reduced support overhead, and improved maintainability, ensuring the documentation accurately reflected product direction and facilitated more predictable integration for developers.
