Description

Your .NET APIs and platforms deserve a solid, high-performing, and future-proof architecture. That's what I've been designing for 11 years.

Senior back-end engineer and .NET architect (since 2014), I work on critical applications: ASP.NET Core APIs, Azure architectures (Cosmos DB, SQL Server, EF Core), and multi-tenant SaaS platforms. I led the end-to-end architecture of the Autogenous platform at Ceva Santé Animale, managing a team of 5 developers, and delivered in production for Sodexo, Bolloré, TUI France, Groupe PSA, and Canon. Today, I'm evolving a multi-tenant B2B SaaS platform in .NET 9: four client portals, a single modular codebase.

What I bring you concretely:

- Robust ASP.NET Core APIs, tested (TDD/xUnit) and validated by review + SonarQube

- Measurable performance: from an endpoint taking several seconds to under 300 ms, with benchmarks to support it

- True Azure mastery: Cosmos DB, SQL Server, data pipelines, change-feed, CI/CD

- Full-stack when the project demands it: Angular, React, TypeScript

Rigor of a software publisher, autonomy of a freelancer. Microsoft Certified (MCSD App Builder, MCSA Web Applications). 100% remote, response within 24 hours.

Let's talk about your .NET / Azure project: describe your needs, and I'll respond with an initial technical assessment.
