I have very solid experience in electronics in general and in using Arduino specifically, I can get most of the hardware from the local market and start right away.
I am professional in hardware and electronic design, if you want to design the system as PCB I can do that for you using my preferred CAD tool Altium or any software you prefer.
I already have libraries for ECG measurments using arduino.
I made several projects using wireless communication, RF, Wifi, Zigbee, Bluetooth so I have the required experience.
I already have most of the required libraries implemented and ready to be used.
I am always available and good in communication with my customers.
I will try my best to deliver before schedule and I will help in your testing.
