About Yann

Senior Data Platform Engineer specialized in designing and building modern data ecosystems on Azure and Databricks. I help organizations structure, scale, and industrialize their data platforms, from ingestion to serving, with a strong focus on performance, reliability, and governance.

With a solid DevOps culture, I implement Infrastructure as Code, CI/CD pipelines, and robust deployment strategies to ensure maintainable and production-ready systems. I also design API-driven architectures (FastAPI / GraphQL) to expose and integrate data seamlessly across business applications such as ERP and CRM.

I bring hands-on expertise in Databricks (Delta Lake, Delta Live Tables, Unity Catalog), Spark optimization, and end-to-end pipeline design, combined with strong experience in cloud transformation programs.

My approach is pragmatic: delivering scalable, secure, and business-aligned solutions while enabling teams through best practices and clear architecture.
