His passion is the development of distributed systems including those which are hosted on Azure. In his professional career, Sergii is mainly focused on development with C#/.NET, ASP .NET Core, Azure Service Fabric and other Azure products. In addition to that, he has also advanced experience working with ASP .NET, WPF and lots of other frameworks written for .NET. Since JavaScript development improved a lot recently, Sergii also became more interested in client-side development and had a chance to work on projects written in Angular 2 and React.
