I made an internet-connected car alarm

BMMPR

As 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.
