Hey, My name is Vivek, I am Software Engineer working around Open Source and Cloud Native technologies around Kubernetes primarily using Go as programming language. In this channel I am going to create videos about Containers, Kubernetes, Go programming language and Software Engineering in general. In these videos I am planning to actually show you things by doing, instead of just talking about them; so that you would actually learn about them and can use them either at your work or as some other place.
