In collaboration with a team working on Enedis’s Linky project, I helped design and implement a Big Data ecosystem using technologies like Hadoop, Kafka, Spark, and Ambari. This was deployed and managed with tools such as OpenStack, OpenShift/Kubernetes, Ansible, GitLab, Jenkins, Docker, and more.
Coding services + tests and associated GitLab CI/CD stuff. They were mostly written in Golang with some in Java (Spring Boot framework).
Writing OpenShift recipes and managing clusters.
Deploying applications on OpenShift and OpenStack tenants.
