I am a full time freelance translator. I am having a good experience in document translation as well as in the CAT tools also. I have worked on many projects that has to be translated on such online CAT tools. Recently i have done a project on Matecat. I can work more efficiently because i am a full time freelancer. I can give up to 6k words as m daily output. But it depends upon the source domain and quality of the source provided to me.
