Worked on the NVIDIA/libredfish repository to deliver enhanced Redfish API support for NvidiaGBSwitch and NvidiaGH200 hardware, focusing on backend development using Rust. The work involved deriving a new switch handler from existing implementations, differentiating chassis types such as the P3809 BMC, and updating related data structures to accommodate new hardware requirements. Emphasized a test-driven approach by adding targeted tests and refining the test harness to validate expanded chassis scenarios, thereby reducing regression risk. These enhancements improved Redfish compatibility for emerging Nvidia devices and established a foundation for future hardware support, demonstrating depth in API development and backend engineering practices.
