    “This is the most undervalued iPhone developer on the whole Actually it was kind of scary to hire the developer with zero rating, but his message was more professional than all top freelancers together. Jang has amazing communications skills and very knowledgable on iOS. We needed re-write the whole camera app and the total price was very reasonable. After we found the issues, Jang fixed them overnight and never disputed. We had 4 revisions of the app and now it is perfect. Because of freelancers like Jang I will keep coming to ;) And don't be fooled by his small rating - he is just new to this platform. Max”
