Worked on the sonic-net/SONiC repository to expand the OpenConfig Interfaces high-level design, updating YANG models to support additional state leaves and configuration parameters. This involved refreshing the mapping between OpenConfig and SONiC attributes to improve interoperability and future extensibility. Addressed documentation quality by correcting Markdown formatting issues in OpenConfig_Interfaces.md, enhancing readability and maintainability without altering functionality. The work demonstrated a focus on both technical depth and collaborative clarity, ensuring all changes were well-documented and reviewable. Utilized skills in network configuration, YANG modeling, and Markdown to deliver both functional enhancements and improved documentation within the project.
