Serdar Oncu, our registered freelance Turkish technical translator, has done and currently doing translation jobs for Applied Language Solutions. In addition I would like to point out that he has a very professional attitude to his work. He is very detail oriented and meets deadlines. He replied to e-mails promptly despite the time differences, which is a key point in our work where tight deadlines are to be met.
