- Solely responsible for design and implementation of smart security embedded system POC from start to finish1. Used integrated BlackBerry secure communication APIs and SDKs2. ESP8266 Arduino module interacted with ultrasonic sensor and SPI camera to detect motion and send video to Raspberry Pi via MQTT protocol3. Node.js and Python were used to program Raspberry Pi to detect faces from video and send secure alerts to users' phones via BlackBerry SDKs and APIs4. System automatically disarmed when it detected a nearby familiar device or correct PIN was entered into keypad- Acted as Subject Matter Expert on new BlackBerry API for both company partners and team members- Wrote multiple technical blog posts to inform the public of exciting new ways to use BlackBerry technology: https://devblog.blackberry.com/en/author/nathaniel-johnston
