    Alexander D.


    Ukraine - Tests: 6

    I am a Frontend Web Developer, PHP Developer and a freelancer. As a freelancer I am open to work with individual customers, as well as agencies looking for a specialist in the fields mentioned above. I specialize in HTML, HTML5, CSS, CSS3, PHP(OOP, MVC, Yii), MySQL and JS (mostly jQuery, but pure JavaScript are not foreign to me). I know what W3C and standards are. I always write a clean, readable code, and I know what an object oriented programming is. I prefer to cut the layout myself, then code it and put as much as I can into CSS. I know crucial basics of SEO and Accessibility. I am doing my best not to use the phrase: “it cannot be done”. I have experience with Responsive Design. I am hardworking, precise, reliable and responsible. For private projects I use the Yii framework based on MVC architecture. I embrace every opportunity of a new challenge - especially one with good documentation.
