Hello, Mainly I'm working as a professional English - Korean and Japanese translator in Upwork. But nowadays, I have interest in the Labeling process in Powershell. About image annotation, I did several jobs before but it was not no difficult jobs. So, if you provide me preferable training, I think I can expand my skills about the image labeling with this job. I can start to work rightaway, and if you allow it, I can work for this job over 40 hours per week. And If you have future annotation jobs especially related with Korean or Japanese, I definitelly help you to work it out.
