I specialize in high-performance website development. I use ReactJS with Flux architecture for this purpose. There is no CMS, that can offer you instant page loading and scalability as my websites do. I will be happy to craft a state of the art product for you using the following techs: ReactJS, Gulp.js, Node.js, Express, SASS.
I prefer responsive "material" design from Google in my projects. Pure colors and intuitive controls allow users to focus on the target actions.
