Our systems collect data from IoT devices and third-party data sources, process ingested data in streaming and batch modes, organize processed data, provide the APIs and UI to access it (analytics platform), or use third-party APIs to manipulate the physical world (automated decision making solution).

Our main programming languages are Python and JavaScript. Our front-end solution is built with technologies such as (list is not exhaustive): React, GraphQL, Flask, PostgreSQL, Docker and Kubernetes, and our data processing back-end includes Kafka, Spark and Airflow. Our production platforms run in the public clouds (Azure, GCP, AWS) and employ related services such as GKE, Dataproc (GCP) and AKS, HDInsight (Azure) to name a few, and we deploy the software in a Continuous Delivery process. We focus on a high quality of our software and all team members take seriously such practices as automated testing and PR reviews.
