May 2015 - Present • 11 yrs 4 mos

Hardware Engineering: High-speed & multi-layer PCB layout (KiCad), differential routing, impedance control, EMI/EMC compliance, power management (PoE, switching regulators). Embedded Linux & Firmware: Custom OS image generation (Yocto Project, custom meta-layers), C/C++ development for bare-metal and RTOS, peripheral driver integration (PCIe, USB 2.0/3.0, Gigabit Ethernet, SPI, I2C). System Architecture: Carrier board design for System-on-Modules (SoM) and Compute Modules, IoT gateway deployment, and wireless networking (ZigBee, Wi-Fi). Professional Experience Highlights / Focus Areas Schematic Capture & PCB Layout: Designed complex 4+ layer carrier boards integrating high-speed digital interfaces, optimizing stackups for maximum signal integrity. OS & Firmware Architecture: Built tailored, minimal embedded Linux distributions for industrial IoT applications and developed efficient firmware for real-time sensor data processing. Bring-up & Verification: Conducted systematic hardware bring-up, hardware-in-the-loop testing, and debugging using oscilloscopes and logic analyzers to validate signal timing and thermal performance.
