    I am seeking opportunities to build robust, well tested front-end solutions that require a lot of JavaScript. Here's a short list of bigger projects I have worked on over the last few years: - ING Developing a single page banking application in Backbone/Marionette. We're also using jasmine, karma, nodejs, express.js, gulp, requirejs, d3.js, jquery and many more. I'm a technical team leader of one of the Scrum teams, responsible for the transfer's section of the app. - William Hill William Hill is one of the largest bookmakers in the United Kingdom. I have developed a wide range of websites that required a lot of front-end scripting. 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.
