Hola, Ana. Muy buena redacción, no cometiste ningún error, pero abajo van mis sugerencias. Good job and let me know if you want any help with your English.

Hi!, I´d like to learn English and to help others learn Spanish

My name is Ana, I´m from Mexico. I just finished college. It´s very important to speak English for better professional development. to improve job prospects. (to further my professional development)
I think that making friends would help facilitate learning.
I hope to help others learn Spanish who are in my situation.
