About this Gig

I am an electrical and electronics engineer based in China with over 15 years of experience in electronics product design. I possess expertise in general electronics, PCB design, analog and digital electronics, and have a strong track record in high-volume product manufacturing. I am proficient in home automation, industrial automation, Internet of Things system design, and embedded system design. Please feel free to contact me for assistance with your projects and design endeavors.


Leveraging China's robust supply chain, I can assist clients in sourcing any required components within China. I can also facilitate seamless PCB fabrication and SMT assembly through JLC PCB. Clients from any country can easily continue PCBA production with JLC.


I typically utilize design tools such as EASYEDA,JLCEDA, Altium, Protel, Proteus, etc. My professional expertise encompasses various technologies including SoC, I2C, C, JTAG, ADC, DAC, MCU, and other aspects of hardware design and development.


I can provide PCB manufacturing files, 3D view files, and can arrange for PCBA production through JLC's processing services.
