  • app4tourguideの画像 Cordova GPS multimedia (audio/video/image/text) walking tour app (zip / sqllite / gps / deviceorientation / leaflet maps / local notifications) $1820.00 USD

    “Working with Ying was definitely worth it. Although it was my first time outsourcing a project it was definitely worth the time spent. There is a learning in communication from my side, as you have to really give thought about every instruction you write. Interpreting my communication in a different way then I had intented led to minor differences in project updates, but cannot be blamed on Ying, especially since they where very quickly resolved and in the end the app we are now looking at and using in the wild is wonderful. I am very happy we picked Ying Yi for our app and will definitely work with him again for my next project. Thank you Ying!”
