About Benjamin

Tech Lead .NET / Azure freelance, I intervene on platforms with high technical and business stakes to make them faster, more stable, and more economical.

I support teams throughout the software lifecycle, from design to production, by structuring the architecture, CI/CD pipelines, and quality practices.

My approach combines technical rigor and business pragmatism: I aim to deliver quickly without breaking, by establishing standards that promote maintainability, performance, and cost control. I take on a transversal role combining technical leadership, DevOps, operational management, and functional coordination with business teams.
