Cloud Data Engineer in Paris
I design and ship governed cloud data platforms that turn complex data into trusted products across AWS, GCP, Databricks, lakehouse, quality, and GenAI-ready foundations.

Platform modernization selected, case 1 of 3.
Modernized more than 50 pipelines into governed AWS and Databricks workflows with lineage, quality controls, reproducible infrastructure, and shared delivery standards.
Built a controlled coexistence layer between Atlas and SAP during a multi-year ERP transformation, preserving shared Commerce models and secure downstream delivery.
Unified finance data for 18 countries and 12 currencies with controlled exchange rates, country-level row security, and group reporting that teams could trust.
Selected experience / 2021—Now
From coexistence during ERP transformation to multi-country finance analytics and lower-cost orchestration.
Atlas and SAP coexistence. Databricks, DLT, Delta, Kafka, Terraform, shared Commerce models, quality controls, and secure delivery during a multi-year ERP migration.
50+ pipelines modernized. AWS, Databricks, Unity Catalog, PySpark, SQL, lineage, access policy, and infrastructure as code.
18 countries and 12 currencies. PySpark, dbt, Delta Lake, Power BI, Kyriba rates, and country-level row security for group reporting.
About 80% lower orchestration cost. BigQuery, Cloud SQL, Superset, and Flask for operational decision support.

Independent AI Lab / Paris
I build practical AI products for public-interest questions, agent workflows, and transparent retrieval—and publish the architecture behind them.
Civic intelligence / RAG / agent craft
“Gravity already clocked in.”
Photo Tetris ready.
Selected product
MonÉlu routes each question to SQL or evidence-backed RAG, then makes the origin of the answer visible.
MonÉlu / Civic intelligence
A production pipeline turns French parliamentary archives into tested dbt marts, a FastAPI service, and a public AI assistant refreshed every day.
