The Backend team is responsible for the cloud platform, including reliability, security and feature development. Our system mainly operates within Kubernetes and most of the components we are working on are written in Go. We stream data from our IoT devices via an MQTT gateway into a Kafka cluster, from where it is sourced by the components that we maintain and evolve. Additional technologies used are Helm, Linux, CI/CD with Jenkins and Google Cloud Platform. The back-end is a sophisticated system providing infrastructure for the AI models as well as a data streaming pipeline connecting the data streams from our IoT devices to our customers and end users.
