The -ita suffix is taken as friendly, as english uses the word tiny, doesn't matter if she's older

Este es _________
Is used when you are introducing someone to a third person, not in the context we are talking about, which (to me) sounds more like when you answer to a knock on the door and say Who's that? It's me
In Spanish we would say ¿Quien es? Soy yo, never ese soy yo.
It feels deviant to me, spanglish-like, maybe more common in central-south america.

Este es ... is not used in Central America. They use soy or habla.

On the telephone:
Hola.
-Hola. Soy Magda. (Habla Magda.)
¡Magda! ¡Que bueno oir de ti!
