About Thomas

I am a.NET developer**, I **designanddevelop applicationsandAPIswithin the Microsoft ecosystem (C#, ASP.NET, Blazor).

I am also comfortabletaking overandmodernizing existing systems**: **migrationto the latest framework versions (up to .NET 10), including from VB.NET or .NET Framework.

I also handle the entireindustrializationpart: setting upCI/CD pipelineson Azure DevOps, automating deployments, code quality (SonarQube).

And I also master theAPI securityandidentity managementaspects (OAuth 2.0, Microsoft Entra ID, JWT / Bearer tokens).

What sets me apart:I'm the type to take on technical challenges that others prefer to avoid. On my last assignment, we had to secure APIs and no one on the team knew where to start. I dug in, estimated, implemented the solution end-to-end, tested it with Postman, and documented everything. It's in production today.

**My areas of expertise**:


Development of web applications and APIs inC# / .NETandBlazor
Security and access management (**Entra ID**, **OAuth 2.0**, **Key Vault**)
**Migrations** to the latest framework versions (**up to .NET 10**, including from VB.NET or .NET Framework)
Setting upCI/CD pipelines on Azure DevOps

Accustomed to remote work for major clients for several years, I am autonomous, reliable, and rigorous. Based in Limoges, remote with occasional travel possible. Fluent English (TOEIC 910).
