Hello,
i think i have the required skills and experience for the task you propose;
I have specific experience in portable devices design and manufacturing;
sensors development and management, embedded systems for medical devices, wireless-based human metrologic data transmission between sensors and man-machines system interface; please see my portfolio, all that we have designed and built is now on the market.
I run a small team of designers and engineers to provide that projects are performed on time and cost effectively.
Our laboratory is equipped to test and optimize applications on Nordic systems, besides to BeagleBone, Arduino, Raspberry, and in general on AVR microcontrollers, Atmel, PIC Micro, Intel, Texas Instruments and ARM.
i can provide a fully functional prototype also, other than technical documentation and CE/US certifications.
Post design assistance is provided with no additional charges.
Thank you for your consideration.
Kind Regards
