I have been programming for over 10+ since 2009. Started with VB6,then to C#, ASP.Webforms, WPF, DIrectX, Unity3D around 2014-2017. Android (Java) since 2017. Slowly getting into Kotlin. For now. My strongest skill is Android and just recently picked up on VueJS. I would bet my life on a firebase backed application. Just focus on development. my stack got to be Android(Java)+Firebase+GKE+VueJs.
