About Raphaël

Hello,

Graduated from an engineering school, I was responsible for applications and front-end/back-end project manager for a major international luxury group for 12 years. I successfully led the transition to a web architecture (.NET, SQL Server, Web Services, etc.) on numerous existing applications and managed/supervised several projects from design to launch.

I have been working for this group as an independent contractor since 2015 for:
- Migrations of existing tools (back-end or front-end) to a Vertical Slices Architecture (in general) with ASP.NET 9 and 10 + EF + ASP.NET Web APIs.
- Migration and extension of web APIs under .NET 10/ EF / AzureAdB2C / Okta
- Design and implementation of an EDA architecture

In parallel, I am training myself to remain operational on the various developments of the .NET ecosystem and I closely follow web development trends in general.

Residing in Reims, I ideally work remotely with occasional travel if necessary.
