Nathan Boulogne

Data Engineer / Analytics Engineer

  • Paris, France
  • Freelance · Full-time

For over 5 years, I've been designing reliable data architectures built to be used, not just maintained. From ingestion to dashboard, I industrialize pipelines, analytics platforms, and CI/CD workflows with one constant goal: bring data closer to business decisions.

Multi-source data ecosystems industrialized, faster access to KPIs for marketing and product teams, analytics tools adopted by the business: that's the through-line across my engagements.
