Who I am

Ten years modeling, integrating and making data reliable — from legacy BI to the open source Modern Data Stack. On-premise, open source, European sovereignty.

Ten years modeling, integrating and making data reliable for banking, insurance and the public sector — first on the BI and legacy ETL side (Informatica, Talend, ODI, SSIS), now pivoting to the Modern Data Stack open source: Dagster, dbt, Airbyte, Parquet/Iceberg, DuckDB, MinIO/S3.

Member of the Edda AI team, in charge of determining what we can do with AI, what we are allowed to do, and how to bring it concretely into working groups — not drop it in as a black box.

The data model first

Conviction: the data model first. Medallion architecture, idempotence and replay at the core of design, observability and specifications before code. On-premise, open source, European sovereignty.

Homelab since 2015

Family self-hosting since 2015: personal data platform (Kubernetes, MinIO/S3, Dagster, Iceberg, OpenMetadata), mail server, Nextcloud, Immich, Bitwarden, private PKI, monitoring, home automation. It’s the practical root of my entire on-prem and open source philosophy — what I advocate at work, I run at home.

Teaching & sharing

I run internal knowledge-sharing sessions and present technical topics at Edda. I mentor juniors (Edda colleagues, Telecom Nancy alumni network). Teaching and sharing are active soft skills for me: explaining technical concepts to non-technical people matters as much as mastering them.

Watchlist

Modern data stack, data quality and governance, AI and sovereign agents, software craft, European digital sovereignty.
