In collaboration with a team on Enedis's Linky, I contributed to designing and implementing a Big Data ecosystem (utilizing technologies such as Hadoop, Kafka, Spark, Ambari, etc.) through the utilization of tools like OpenStack, OpenShift/Kubernetes, Ansible, GitLab, Jenkins, Docker, and various others.
Coding microservices + tests and associated GitLab CI/CD stuff. They were mostly written in Golang with some in Java (Spring Boot framework).
