    My career as a web designer started seven years ago in which time it has proven that even though I am a good graphic designer I am even better at coding and slicing. HTML, CSS and JavaScript are the areas in which I excel but I am also familiar with back end development languages like Ruby(Ruby on Rails) and PHP. Also, I am ready to learn new ones and expand my current knowledge of the fore mentioned as needed to the point where it makes me do my job faster, better and more efficiently. That is the way I dived into web programming in the first place and started to like it through the learning process. As an individual, I'm the person that stands out from the crowd. If you want the same for your business, then I'm the professional you should hire! LinkedIn: https://www.linkedin.com/in/sinisakusic Github: https://github.com/kusic  less
