Currently only in a technical advisory role. Founder, former CTO & V.P. of R&D, but actual duties included hands-on embedded SW/HW & mobile development. Developed FDA-compliant embedded Bluetooth Smart (BLE, Low Energy) software/hardware (in C for STM32, Nordic nRF51/nRF52 ARM Cortex M4/M3/M0+ using Keil & IAR Compilers), and Android/iOS SmartPhone/Tablet apps for the revolutionary, multi-award winning Pancreum "CoreMD". Managed engineering staff. This is a rechargeable lithium coin cell battery-powered, IoT wearable device that functions as an open-architecture, publicly-known interface & infrastructure "hub" (1.5" diameter, with multiple connectivity capabilities). Other wearable, low-cost, disposable diabetes management medical devices such as a continuous glucose monitoring sensor, an insulin pump or a glucagon pump (All 3 = an artificial pancreas) may be connected to it. Non-diabetes applications such as physical activity, environmental, body temperature, blood pressure, pulse/heart rate, fetus activity sensing can easily be concurrently performed. Other sub-cutaneous drug/fluid delivery/infusion pumps for pain (or other chronic condition) medications, amylin/symlin, etc could also be connected to the CoreMD to form a multitude of medical device systems.
