Raymond Philip H.

I am an Electronics Engineer with 10+ years experience in designing circuits and PCB for embedded systems from conception to realization. Systems prototyping is both my hobby and profession. I have helped clients in realizing the system they have conceived to their full satisfaction. In addition to designing the system, we can build the PCB in-house, design and print the enclosure, test and debug the system, and deliver them to you as a working prototype. Looking forward to working with you.
