The client is one of the largest telematics organizations on the market, offering solutions for fleet operators and UBI-oriented systems for insurance companies. We took the role of an external innovation lab to develop the backend for a prototype smartphone-based telematics system to open up new markets for the client. Our solution covered developing a fully functioning, scalable system that collected various data and translated it into individual driver scores. The system went live as we performed multiple production deployments. The system had 100k+ users a year at its peak, processing hundreds of requests per second.
