PROFILE
Ericyang-wiwynn
Worked on the facebook/OpenBIC repository, delivering targeted improvements in embedded systems and sensor calibration using C. Developed a sensor threshold tuning feature for Sentinel Dome, lowering the MB_INLET_TEMP_C UCR threshold to enhance temperature monitoring accuracy in line with Meta thermal team requirements. Collaborated cross-functionally to validate changes through formal test plans and PR workflows. Additionally, addressed PLDM messaging reliability by increasing the retry count and improving error logging, ensuring robust event delivery during high-load scenarios such as blade AC cycles. Demonstrated skills in system programming, data-driven calibration, and end-to-end traceability, focusing on reliability and alignment with customer needs.

Jun 1, 2026June 2026: Improved PLDM messaging reliability under high load for Facebook/OpenBIC. Increased PLDM_MSG_MAX_RETRY from 5 to 20 to ensure delivery of PLDM events during blade AC cycles, and upgraded retry-exhaustion logging from LOG_WRN to LOG_ERR for better visibility. Delivered via commit a1098fbafda369204bb8f1f43121defb30a8fd8d and PR #2724; validated through build/tests and code review, enhancing resilience and reducing risk of missing SEL entries during busy startup sequences.
