PCB design Project

This is my 2nd project with Chenglie L. and he worked well for firmware task but couldn't finish PCB design project. he was not professional through out the project and simply delayed it for a week and always ask for more charges. I will not recommend him for any PCB work as it seems even he outsoucerd these task from someone else. He is not able to show any update till now and blaming the behaviour of my colleague . Please save your self from such freelancer.

PCB designer for fastest PCB design. -- 2

Chenglie has really put a lot of efforts into the project and managed to finish it perfectly according to the requirements in no time. Hands down the best freelancer that I have worked with. Amazing all-around experience, truly an expert who was able to complete the task which others couldn't. He is very precise and consistent. Communication was fluent and prompt. As opposed to majority of freelancers, his English is on a native level. In general patient, tries hard and explains things in-depth.
