Start learning and developing React components in July, 2014. I have strong experience in integrated 3rd-party JavaScript libraries to corresponding React components. The spirit of React is provide **stateless component** to customers, so it's really important to keep this in mind when integrating 3rd-party JavaScript libraries.

I have clear understanding in JavaScript, as well as strong work experience with its extension languages like LiveScript or CoffeeScript. I only wrote JavaScript with its good parts. You can say that other parts are all root of cause of bugs. Besides client side scripting, I also use nodejs-based asset manager to help me pack up assets (JavaScript, CSS, HTML, etc). Feel free to ask questions about JavaScript!

I have setup several projects that using webpack as a main bundler. Loaders including jsx, babel.js, sass, less, images, fonts ... etc are used in these projects. Deploy production-ready assets to gh-pages, s3 or cdn. Configure correctly for your react-hot-loader to work with existing node.js server, with the support of testing over LAN on your mobile devices. Bundle your react components for server-side rendering is also supported by webpack.

I have some experience in developing nodejs based web app using expressjs and koajs, as well as some understanding in ORM like mongoose or sequelize. I've played with nodejs 0.11 for a while and got excited about generators to come. Generators give great advantage on flow control. As for nodejs 0.10, I almost use Promise API as much as possible. This make our code more easily to reuse and write, and it's event future compatible!

It's as long as my experience with web development. For personal projects, I will use more lightweight markup languages like jade or slim. As for css, I started with Sass and have been stick with it for three years.

I've always using Git and GitHub for both public and private repos. I also have experience to write clean and clear commit message, as well as creating readable branch tree. I believe being able to use Git well is the basic foundation of a great developer.
