"switching" give the impression of let go the web. I say "adding".

I work freelance for more than 20+years and have done almost all: Windows Apps, Web Apps, Mobile (iOS, Android), Cloud, nosql, sql, utilities, etc.

Adding an extra to what you have make you stronger. Is a big plus for me to say "I know this and that and that...".

Of course, I have my preferences and strengths, but I can fit in almost any project.
