I am an EE with many years of hardware and software design experience. I have my own design business and was overloaded with projects and had one with a new (to me) embedded processor and no time to become familiar with it, so I went to Freelancer and found Jian. I found him to be as competent as any engineer I've had the pleasure of working with (better than most!). He had both the skill and product familiarity to do the job, the self motivation to perform in the total absence of any direction, and the patience and communication skills to drag me through the setup of a working prototype system and provide me the education and tools needed to support it. It was a true pleasure I would not hesitate to repeat!
