Dominique Rondé is a big data pilot and an employee of the InsureTech startup freeyou. He works with all sorts of technologies around the topic of „big data“. However, most of his „flying hours“ he has collected on the Apache Spark, Confluent Kafka and DataStax Cassanda. In everyday life, he also deals with the possibilities of statistical analysis – in short, data science. As a true Java nerd since 2002, he programs most of the jobs himself and runs them on cloud architectures.
