I have been working as a professional translator for more than 30 years, and in many situations: five years at major manufacturing plants, ten years as a proof reader and chief translator in translation agencies, and 15 years as a freelance translator, plus several times a leader of freelance translators for large-scale projects. I do translation very carefully, checking unknown/unfamiliar expressions as much as time permits and attaching comments for any expressions I am not sure.
Please trust my quality and sincerity.
