Android / IOS Senior Mobile Developer / Architect

I'm a high-quality native iOS and Android apps wizard. I'm Oracle Certified Java developer with Master's degree in CS with 12 years of experience in developing not only Android and IOS projects, but also different projects that made me a great architect, complex issue solver and UX/Features improver in all aspects with experience in huge amount of libraries and frameworks such as Firebase, Parse, Spring and much much more. I'm the best in Android and iOS app development as I'm up to date with new technologies, features, and tricks that Google team or Apple team announce. I have led all projects from scratch up to release with a full understanding of OOP, SOLID, optimization, analysis and user experience. I'm proud of apps I made: GuruShots, LiftDay, LiveMaster, and others, so thanks to my clients that trusted me and gave me that opportunity. NOTE: Please do not be surprised by the large number of described technologies, that's even not all. 13 years is more than enough to be able to work with so many technologies!
