Senior Mobile Developer

Experienced iOS/Android Developer in Swift / Java who has successfully delivered several apps to the App Store (Apple and Google Play Store) on time and on budget. I am familiar with most of popular design patterns (MVC, MVVM). I have vast experience working w/ Social networking apps, Location/Map based apps, Fitness apps, Food ordering apps, Mobile games, ARKit, CoreLocation, Alamofire, as well as several other popular 3rd party SDKs. As a reliable Top-Rated Plus developer with over 8 years of experience, I’m committed to the highest industry standards in all the work I do. I also pride myself on possessing a high level of professionalism, maintaining excellent communication, meeting and exceeding client expectations, and providing solutions for problem-solving in a timely manner. I come highly recommended from all my previous clients and hope that I can continue to do so if you choose to hire me for your project. Got an idea for the next big thing? Have you been dreaming about creating your own application? If you have wireframes and need to turn them into a functional application or perhaps just a notebook with drawings of your designs, I can assist you in turning that creativity into a polished and published application for both Android and iOS platforms.
