Task

Build a kicksharing platform in which thousands of scooters send data, receive commands and serve user rides at the same time.

The service had to withstand peak loads and reliably control every device in the city.

Client

Karusel is an e-scooter rental service.

What we did and how

We developed the whole platform — from device firmware to the user app — as one team.

  1. 01High-load Go backend for rides and fleet management
  2. 02Firmware for the scooters' IoT devices: connection to the platform and telemetry
  3. 03Dispatch back office: fleet monitoring and maintenance
  4. 04Mobile app for users

Result

More than 10,000 scooters run on the platform. The project showed that the ESTESIS team reliably runs an IoT product end to end: hardware, embedded software, cloud and app.

The whole product — one team

Four layers that different contractors are usually responsible for. Here ESTESIS built each of them.

Finding a scooter, renting, paying and ride history.
