    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

    Currently I am focused in creating rich client-side apps using JavaScript advanced techniques, CSS3 and HTML5 features. I am keen in creating perfectly looking user interfaces and visualisations with help of D3,js and my great experience with UI/UX. Using best practices and a streamlined workflow I manage to work on complex solutions that include hundreds of user-cases and apps views that are often created as real-time dynamic apps. I use TDD where applicable in my frontend engineering work. Being a problem solver for my clients I am sure that clean, semantic markup and content-driven, responsive layouts are the way forward. I believe in building sites that are device-agnostic, adapting layouts and experiences to a user's viewing environment. I am a fan of progressive enhancement in my work. Having solid backend development experience with multiple languages like Python, C# and JavaScript I try to imagine and see the whole picture of projects I work on.  less
