At Teleperformance (TP), I lead the Data Engineering, BI and Analytics function, shaping data architecture and evolving the Azure Databricks and Data Lake platform. I build governed self-service capabilities and drive data quality and AI initiatives.

At Globex International, I built a placement intelligence pipeline that brings broker-system data, policy documents, email and placement workbooks into BigQuery, using Claude extraction and fuzzy matching. I also automated renewal support with Gmail API, Gemini and BigQuery.
