About me
Hello.
Experienced Hardware and Embedded Systems Engineer with extensive expertise in high-speed multilayer PCB design for RF, FPGA, and SoC-based platforms.
I specialize in developing reliable, production-ready hardware for complex embedded systems, covering the entire process from architecture and schematic design to layout, signal integrity validation, and manufacturing support.
My technical strengths include controlled-impedance routing, high-speed interfaces such as DDR and PCIe, power integrity optimization, and EMI/EMC-aware layout practices essential for robust real-world operation.
