About me
I am an Embedded Hardware Engineer with 15+ years of experience in embedded systems, PCB design, and hardware bring-up. For over 10 years, I have specialized in high-speed multilayer PCB design, including FPGA, DDR4/DDR5, PCIe, SDI, and other high-speed interfaces. Based in Shenzhen, China, I can manage the complete hardware development process—from schematic and PCB design to JLCPCB ordering, component sourcing, PCB/PCBA production, inspection, hardware bring-up, debugging, validation, and final delivery. I provide a complete design-to-working-prototype service. Thank you for your attention.... Read more

    Zhai’s PCB design work was absolutely outstanding. Extremely professional, precise, and genuinely brilliant — the final design was so clean and well executed that there was simply nothing left to correct or improve. I’m very impressed with the quality of his work and will definitely work with him again on future projects. Highly recommended!!!!!
