We solve complex multi-physics and electro-mechanical issues to deliver lightweight, wearable consumer devices that seamlessly integrate spatial audio, display optics, eye/head tracking, high-performance silicon, and wireless connectivity. Design and optimize power distribution networks (PMICs, DC-DC converters, battery management) and high-speed interfaces (MIPI CSI/DSI, PCIe, USB-C, LPDDR) to meet strict power, thermal, and signal/power integrity (SI/PI) limits.
