About Guillaume

I have been working on .Net applications since version 1.0 of the framework. I have worked on Web applications (ASP.Net, MVC, Vue.js) for intranets or back-offices, relying on Oracle or SqlServer databases. I have also worked on Winform, UWP applications and am currently developing an application using MAUI. I also have DevOps basics, having participated in the implementation and used the on-premise versions of TFS then AzureDevops.
Implementing cloud solutions is among the skills I wish to improve in the coming months.
