Hi! I am trying to apply for a job position, my resume must be in English. I just one to double check if my grammar is correct or if I can improve something.  This is what I have written. Feedback, please!! Thank You!!

 I have been a call center agent for more than  three years now, I'm looking for a good  opportunity to grow as a professional, I would like to work in a very strong company, that gives me the possibilities to learn and develop myself. I'm the kind of person who can't stop learning, also I want to expand my knowledge to other areas, that's why I'm studying web design and programming.
