I am a highly motivated and skilled full-stack developer, passionate about building over 7+ years. My skill set allows me to see task from different angles and choose best solution. I like to be on the bleeding edge technology, but I can also use more classic ways to solve problem depending on client's preferences and timing. My primary personal skill is to apply my best efforts to find appropriate solution to solve client's problem. And my wide range professional knowledge is the key to achieve the goal. I never cease to learn new things. I always move on. My major development areas are : - React.js, React Native, Xamarin, Ionic for hybrid mobile app - Objective-C/Swift and Java for native iOS/Android - Backend development using Node.js, Ruby on Rails, PHP - Social Frameworks, Backend & Clouding Service, Payment Gateway Integration - GPS Tracking, Map Service Integration - AWS EC2, S3, AWS Lambda, Firebase
