I made an internet-connected car alarm
BMMPRAs a consultant, I turned my client's idea for an internet-connected impact-sensing car alarm into a shipping product. He's sold millions in revenue.. wish I'd asked for equity 😂
BMMPR plugs into the OBD-II port, and has cellular and bluetooth connectivity, GPS, and an accelerometer. I designed all the hardware and wrote the firmware to connect to the mobile app and an AWS backend.

The journey of 1000 miles begins with one giant breadboard covered in evaluation boards
