What's the difference

Most of all I like implementing challenging tasks that is why mobile software which I have developed for more than 4 years became my second nature.

The mainstream of mobile development: iOS and Android are the core of my competency.

Data storing: SQLite, Core Data, file storage
Data languages: JSON, XML…

Work History & Feedback

Iphone developer (accelerometer, journaling.. ready for a challenge?)

“I had this idea for an iPhone app and decided that Alexandr and his team would be a good fit to build it out. Other personal projects came along and I had to put this project on hold, but I was impressed by the professionality and dedication they had towards this project.Excellent communication, and they were always there when I needed them. I would not hesitate to contact these guys again when I'm ready to continue the project, which I hope will be soon. In fact, I would not hesitate to contact them for all future projects.”
