I am mainly a full stack JS developer, usually using technologies such as React for front-end and Node (Express Framework for Web Servers) for back-end. Recently I have been doing a ton of research on all things C#, messing with unity, xamarin, building mvc apps, razor page sites, web api's, watching latest conv tutuapp entions, panels, readin tweakboxg articles etc....
