Riad in a few words

Ik ben Riad, al meer dan 14 jaar een C# .NET-ontwikkelaar.
Tijdens mijn carrière heb ik in verschillende configuraties gewerkt: grote teams (15+), kleiner scrum teams (minder dan 8), en ook als solo-ontwikkelaar. Mijn typisch technisch stack is een .NET applicatie (web of mobiel) met een .NET (Core, 5 of 6) backend gehost op Azure. Ik heb natuurlijk ook ervaring bouwen van CI/CD op AzureDevOps.
