When we started, the operator was a team of about ten people with a network in full expansion. It was looking for a team that knew EV charging and would stay alongside the company as it grew.

Charging stations talk to the central platform over OCPP, and the platform exchanges sessions and tariffs with other operators through roaming protocols. These are young standards that don't cover every real commercial case, and they run over mobile connections that sometimes drop. Between the user's app and the charging station sit several systems, often run by different companies, and every hop has to be traced and made reliable: when a charge doesn't start, the user notices right away. Alongside it ran the energy-trading platform, with its own rules and timing.
