Publicity Providers, Inc. says,

M. designed a terrific prototype proof of concept board for our company. We are not Bluetooth experts, nor are we experts in HF. We gave M. a simple hand drawn drawing of how we thought the circuit would function, and he understood our goals well, and quickly developed an efficient circuit for us. In addition M. created the Gerbers and the BOM for us. M. obviously has deep knowledge and experience with Bluetooth, ISM, and the high frequency driving of components. M. achieved a proof of concept board for us in a handful of days, while I had predicted that it would take several weeks. Thanks, Allen.
