Thanks for your viewing my profile. I have wonderful experience about Windows, Linux, iOS and Android development for over 10 years. Since I have started app development, I have been spending every spare minute by writing code and learning everything on mobile app development. I experienced knowledges for social medias such as google, facebook, twitter, wechat, instagram, parse and firebase, geo-location and google map, music, video, and picture management, voip, chatting, dating, push notification and in app purchase. I always aim to maintain a long term relationshop with my clients. Whether you've lost your original developer, need additional resources, or want a brand new app, I can step in and take over wherever you need. Best regards!
