About me

Data engineer. I build pipelines that are tested, monitored and built to last.

I'm a data engineer with more than six years of experience designing and running data integration pipelines for companies in finance, insurance, mobility and marketing, as a consultant at Epsilon France (Publicis Groupe) and then as a data engineer at RiverBank and Corum L'Épargne.

I've worked in both worlds: distributed Big Data processing with Spark, Scala and Hadoop, and more traditional platforms built on SQL, Azure Data Factory, Apache NiFi and Google BigQuery. Across them, I focus on what keeps pipelines healthy in production: automated tests, monitoring, data quality and code that the next engineer can maintain.

Today I work on the modern lakehouse stack. I first worked with Data Vault on Corum's data platform; my latest project integrates six European company registers on Databricks and AWS with a medallion architecture, SCD Type 2 history and automated data-quality gates, and I earned the AWS Certified Cloud Practitioner certification in October 2026.

How I work

Explicit over implicit. Declared schemas instead of inference, configuration instead of copy-paste, and failures that are loud instead of silent.
Model for change. Sources change their formats and their data. I separate raw history from business rules so a change in one place doesn't break everything downstream.
Cost-aware cloud. Serverless where it fits, and incremental work where it pays, like geocoding only the addresses that are new.

Beyond data

I'm a tenor and sing whenever I can, I train CrossFit, and I'm endlessly curious about nature, from rivers and forests to the deep ocean.
