I develop fast adaptive sites on the most modern technologies, use the react.js. I take out the entire front-end of the site for outsourcing. I have a team of 6 professional developers. We use a stack of technologies: - HTML, CSS, Javascript es5, es6, es7 - React, Redux, Redux-saga - React-bootstrap, Scss, jquery, ajax - Node.js, Express.js, MongoDb, SQLite - Snap, d3.js - SVG, Canvas - json - Docker - Git, Github - Web-sockets - Linux - Zeplin, Photoshop, Avocode Sites also adaptive to all types of mobile devices, this is very important, because for today up to 70% of visits to sites are accounted for by mobile devices and the correct adaptive design is the key to success.
