PDF & Editable Files

My translation pairs are English-Spanish and English-Catalan, but I may also translate into English for select medical projects.


I work with Memsource — a computer-assisted translation tool — to analyze, translate, and review editable files.


Optic character recognition and transcription help me convert non-editable files into text. I can type up to 100 words per minute!
