I have been developing software for 7 years. During these days, I produced over 5 national projects, more than 10 from Japan and 10 from other countries. Especially, I am very good at developing Web applications using Node.js, Java and PHP. Neither Front-end nor Back-end developing is a problem for me. I also have more than 2-year experience with AmazonAPI and profound knowledge about database designing and security. And I have rich experience of developing a lot of Unity3D, Cocos2dx, and Xamarine projects, I mean, mobile and Web apps and games. If you would kindly send me detailed requirement specification of your project, I could guarantee high quality of the product.
