Description

Senior Data Engineer with over 6 years of experience in Big Data and cloud platforms (banking, telecom, retail, public sector), specializing in setting up robust pipelines, reliable data models, and dashboards for steering.

I design, industrialize, and optimize data architectures (Spark, Databricks, Azure, Scala, Python, SQL) to serve business teams, ensuring data quality, performance, and traceability. Additionally, I leverage this data foundation to deploy targeted AI use cases (LLM, internal assistants, RAG) when they provide concrete benefits.
