    Web designer & developer

    Lithuania - Last active: 1 month ago - Tests: 5 - Portfolio: 2

    I'm a front-end and back-end Web Developer and UI Designer based in Lithuania. I have a passion for creating clean, interactive, responsive and user-friendly web interface, developed by scalable, modular and functional code. Ever since the beginning of my freelancing I've been keeping up with the cutting-edge web technologies, aiming to produce best possible user experience. For most part I have used to work with front-end development. You can find examples of my web designs and logos on https://99designs.com/profiles/yzys. I am trying to find small to average projects to work with. As I am already working part-time and studying for my master's so I don't have time for full time job. I have developed a few websites using HTML, CSS, jQuery, PHP, and MySQL including sites for startup companies like http://veggo.lt.
