    Thank you for considering my profile. I have have been developing iOS & Android apps over 5 years. I can help you develop iOS , Android apps, Backend apis. My another major skill is web and mobile GIS application implementation. Most of my clients have been satisfied our job results. Here is one of reviews from my clients. - “Excellent developer. Fast, responsive and super impressive results” - I've started my professional experience as C/C++ developer in 2005. During the 4 years I developed a low-level system software for Windows/Linux platforms. In early 2009 I've set my eyes onto Apple devices and started developing mobile software. And I am working in GIS apps with a great GIS expert who has 10 years experiences. I am crazy in code quality - it makes me happy when I feel I do a perfect job. Also some of my personal projects I've shared to open source community. I can lead many developers for the project too. Looking forward to working with you and good luck with your project.
