Flexible PCB Design

Tan is an exceptional freelancer with the eye for great PCB designs. There was a little communication issue in terms of english language with him but if you can make that 2% adjustment then it's worth it. He is better than most of the US and Indian guys I regularly hire and I plan to hire him again very soon
