Coming from C# Dot.Net Web ecosystem (MSSQL, JS, jQuery, CSS), working on Asp.Net and Mvc.Net projects, Moved to Mobile native development (iOS, Mac - ObjectiveC, Java for Android), for a couple of years and then, back to Vanilla JS for web SDK development (+extension). Currently deep diving into React, TypeScript and what's in between.
The focus was and is, the data-security field.
