About Loris

I build end-to-end data systems, from pipeline ingestion and automation to the strategic analysis that drives decisions. My hybrid background (10 years in commercial and ops management + modern data stack) means I never lose sight of what data should produce: a decision, an action, a measurable result.

What I bring concretely: automated pipelines that run without manual intervention, actionable dashboards and reporting, and a business perspective on your data, without having to hire a data engineer and an ops manager separately.

Latest project: Le Filon (lefilon.immo), a live real estate analytics platform. Airflow, dbt and BigQuery pipeline, Streamlit web app, public REST API, freemium model. From raw data to investment decision, fully automated.
