Haiyi Wen contributed to the welovej/azure-rest-api-specs repository by developing and refining Azure App Configuration APIs, focusing on both data and control planes. Over six months, Haiyi delivered new API versions with features like tag-based filtering, caching headers, and Azure Front Door integration, while also stabilizing and cleaning up API specifications. Using TypeScript, YAML, and REST API design, Haiyi improved security by removing SAS tokens and enhanced maintainability through documentation updates and resource scope reduction. The work addressed real-world integration issues, such as reference handling bugs, and demonstrated depth in API development, specification management, and cloud resource management.

October 2025 (Month: 2025-10) — Azure/azure-rest-api-specs: Implemented Azure Front Door configuration support in the App Configuration API (2025-06-01-preview) for the Azure App Configuration resource manager. Delivered API version 2025-06-01-preview enabling Front Door configuration with a new property to specify the Front Door resource ID. Updated README to reflect the new API version and included example JSON files for private link resources. The work is exemplified by the commit 946d10b261b2b6c430fa3b76001fe20887a97f2c. This enhances modular deployment, improves customer ability to adopt Front Door-based routing via the App Configuration API, and aligns with private-link security patterns. No major bugs reported in this scope.
