Passionate about technological innovations, I strive to design and implement sustainable solutions that effectively address the challenges of large organizations.

A fervent advocate of the DevOps culture, I played a key role in industrializing processes and maintaining platforms for Coliposte's IT department. As a Lead DevOps, I not only provided Level 3 support but also supported and guided a dynamic team of developers and infrastructure specialists of over 30 people. I had the opportunity to train several colleagues within the Core team and make significant contributions within development squads.

At Crédit Agricole, as a DevOps specialist, I consolidated my expertise with a focus on BigData and Streaming. I actively participated in the development and implementation of offerings based on Apache Kafka, such as Topic as a Service and on-demand Kafka Clusters, tailored to the specific needs of different group entities. I also designed tools to ensure the sustainability and efficiency of these solutions. My contributions were recognized, allowing me to discuss our advancements at several events organized by Confluent in Paris.
