I have been a very successful app developer for over 7 yrs, working for individuals all over the world. Since I have started iOS and Android app development, I have been spending every spare time writing code for the iPhone, and learning everything on mobile application development. Additionally to development of new apps, a lot of the work I do is on-going maintenance of existing popular apps. I always aim to maintain a long term relationship 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 the wherever you need. Thanks!
