English to Spanish (Spain) Translator

I've spent the last fifteen years working full-time as an administrative clerk for different companies. During that time, I've logged thousands of hours doing everything related to the administrative process, including copy, editing, proofreading, data entry, search content and translations. I'm also very familiar with English grammar and usage and have no trouble adapting to various style guides.
Spanish and Catalan are my native languages and I am fluent in English, certified with the Certificate in Advanced English.
