About

CPU subsystem firmware design, development and Silicon debugs. With a focus on power and performance, my work has direct implications for system stability, reduce latency and Subsystem firmware readiness. Identify the bugs in early stage of Pre silicon and same time make sure firmware is ready before silicon comes up. My previous tenure at Intel Corporation allowed me to lead in the Power management firmware development of server graphics cards, emphasizing the importance of power management in high-performance computing from Pre Silicon to Post Silicon. Our team advanced Intel's capabilities in meeting rigorous power and thermal specifications. This dedication to excellence is what I bring to each project, aiming to continually push the boundaries of technology.
