My Wikipedia user page in es: (where I'm an admin), en:, fr: and ja:. I'm in es: about 95% of the time.
I have a lot of work in the Spanish Wikipedia, but I will come here from time to time to translate parts of Translation requests/NL-1/Es: . Most of my experience as a translator ^^ comes from my translations of articles from the English (or rarely French) Wikipedia into Spanish. There are a few words or phrases that I don't know exactly how to translate... in that case I'll mark the original phrase in English as a comment for a proofreader to correct.
I have no formal education in other Romance languages similar to Spanish, like Portuguese, Catalan, or Italian. Due to mutual intelligibility, I can read and translate decently fairly simple texts in those languages into Spanish. I can't write in those languages, of course.
