    HTML5, WordPress, Responsive, Bootstrap, AngularJS, Frontend Rockstar

    Vietnam - Last active: 2 days ago - Tests: 2 - Portfolio: 5

    Professional guru with 6+ years of experience in web development. I can work individually or quickly put together a team of highly experienced developers and designers. I used to be a full stack developer. For the past 3 years, I have been focusing on only two things: - Front-end development - WordPress As I focus only on this, my turnaround time is extremely fast and it would help you save a lot of time and cost. With the quality guaranteed, it would also save you much effort of coming back and forth to test for bugs. And as a full stack developer, I know exactly what a back-end developer would need, so my front-end code is always prepared for all the cases. The code is high quality, semantic, well-documented, clean with minimum duplication, readable with white spaces, and easy to maintain and extend. I'm also a pixel-perfect person, but since the product must work perfectly on all screen sizes, I'll take initiative and amend if it's off the grid. I can quickly adapt a desktop design to tablet and phone screen sizes. My goal and passion is making responsive sites (compatible with tablets/mobiles) with focus on performance, SEO optimization, and user experience (UI/UX): - HTML5, CSS3, CSS 3d transition. - SASS/SCSS, LESS, Neat/Bourbon, Foundation, Twitter Bootstrap. - Javascript, jQuery, Angular JS. - Building single-page web applications using Angular JS which work seamlessly with RESTful API web services. - Git, Github, Bitbucket, Subversion (SVN). - Very proficient with Photoshop. - I have my own server for demo purpose and a private Git server in case you need.
