Certified GCP Data Engineer, passionate about automation and performance, I have designed and industrialized data platforms for clients such as Qualcomm, URSSAF, and Crédit Agricole.
I work on cloud migration (GCP, Azure), ETL/ELT pipeline development (PySpark, Apache Beam, Kafka, BigQuery), and infrastructure as code (Terraform, CI/CD, Ansible).
My skill set covers cloud architecture, monitoring (Grafana, Prometheus), IAM security, data governance, and FinOps optimization (-40% Cloud costs at Qualcomm).
I bring both technical and strategic vision, translating business needs into performant, scalable, and secure data solutions.
