I am savvy web developer with 8+ years experiences in web development especially 5+ years in Ruby on Rails. Since 2007 I have developed a lot of senior level applications using primarily Ruby on Rails including e-commerce sites, inventory management systems, scheduling systems, forum applications and other fulfillment systems. I have deep knowledge background in HTML5, CSS(twitter bootstrap 2.x, 3.0, zurb foundation), Javascript(jQuery, backbone.js, knockout.js, d3.js) and I have enough experience of working in leading and managing the web applications. I started my developer career about 10 years ago, with C/C++ development. I built several applications with C/C++, .NET framework and investigated 3D technologies with DirectX & OpenGL. I built navigation program with DirectX with Google 3D datas and textures.
