    Russia - Last active: 22 hours ago - Tests: 9 - Portfolio: 27

    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 visualizations 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.

    I am seeking opportunities to build robust, well tested front-end solutions that require a lot of JavaScript.

I had a chance to work on a truly scalable solutions as the websites were in 24 languague versions. - AQA AQA is one of five Awarding Bodies which are recognised by the regulators of the public exams systems for England, Wales and Northern Ireland. I had the privilege of working in the AQA office in Guildford directly with the kind and professional AQA team who had a really positive attitude about the project. My work focused mainly on the implementation of a cut-up, which involved converting an HTML and CSS template into the proper syntax for the CMS, provided by a third-party company whilst reporting to the Project Manager for AQA's project.
