Nathan Boulogne

Data Engineer / Analytics Engineer

  • Paris, France
  • Freelance · Full-time

With over 5 years of experience, I turn business challenges into reliable, actionable data architectures. Since 2021, I've been building data pipelines, robust platforms, CI/CD systems, and analytics solutions, always with a focus on business impact, not just technology.

In practice, I've industrialized dozens of data sources, accelerated time-to-insight for marketing and product teams, and delivered analytics platforms that business stakeholders can actually use, not just pipelines running behind the scenes.
