Hello,
I am Anthony. I am working FULL TIME as freelancer. I have double degrees in Mechatronics and Applied Science fields.
I have very good feedbacks on freelancer.com . Please check the link at the end and review my feedbacks. So you can get an idea of my work.
I have the capability to guide you until the manufacturing stage. I have many contacts in China and can help you to setup there if you are gonna mass produce your product.
I have worked with CC2540/41 before and I have access to sample ICs. I have the development kit also if you want to do any stack modification. I can supply with two sample bords or else prototypes if you want.
