Freelancer Overview

I have 5 years of experience with data annotation, I started with small projects at Appen, Lionsgate, Telus and Transperfect, they were about text annotation to train machine learning and one for image annotation. The last couple of years I started working at Borzalabs, part of Cisco Company as an audio annotator and the last year I started to work for ActiveFence for text annotation in English and Spanish language.
