I have worked with Android since 2009. I have participated in more than 50 Android projects from small to large one. I worked for different companies in VietNam, Netherlands and US in different industries: production, outsourcing, offshore and startup. Since 2014 I started to work with iOS (using Swift). From then on, I have taken part in more than 10 projects. I can work in projects of any area of experts: Image processing, Social networking, Utilities, Lifestyle, and especially Games. I also worked in HTML5 front end development in which I mastered HTML5, CSS3, Javascript and JS frameworks/libraries like: jQuery, Bootstrap, AngularJS, Sass, Less, NodeJS. In my works, I always use modern software development process: Git (Github, Bitbucket), Unit Testing, Alpha Beta Testing, Continous Integration (Jenkins). *****When I develop your app, you will also get Crashlytics integration (Crash report), Google Analytics integration (to have report on user's installation & behaviours) FOR FREE.
