About Sébastien

I am a developer passionate about the .NET platform with nearly 20 years of professional experience in service companies and startups. I have had the opportunity to contribute to a very wide range of projects including Web applications (ASP.NET, ASP.NET Core / Azure), Desktop (WinForms, WPF) and mobile (Xamarin, UWP), in teams of 2 to 15 people.

In addition to this technical knowledge, I offer my clients my teaching skills: I have been providing training on the .NET environment since 2011, whether they are "formal" training courses within training centers or integrated into development missions.

Although I am mainly focused on the .NET platform, I remain open to any technology or tool that can add value to the projects I participate in.
