Back to original languageAbout Juba
Hello! I introduce myself: Juba, Data Engineer for a little over 5 years now. I had the chance to work on various large-scale projects in Banking/Insurance (Société Générale, BNP Paribas, AXA), as well as recently in rail transport (SNCF Voyageur). This allowed me to work in different functional environments (Credit Risk, production data, insurance).
I also acquired strong expertise in Scala and Apache Spark, on the Azure and Databricks cloud, but also on other equally interesting technologies.
