    Russia - Last active: 3 days ago - Tests: 4 - Portfolio: 17

    I develop applications and games on flash for about 4 years. Also I create an standalone AIR applications that are can be easily launched on Windows, Mac and Linux systems. I am individual developer, not a team player. Mostly I doing all job by myself as client side so server side. Back end usually includes PHP and MySQL. Export graphics from Corel or Photoshop that's what I'm doing too. I am most interested in casual game projects, because I get a lot of pleasure by the time of their development and testing. I don't create design - programming only.

    JavaScript/React/Angular/D3/CSS3/HTML5 Frontend Developer and Designer

    Russia - Last active: 1 day ago - Tests: 9 - Portfolio: 11

    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.

    My unique approach to financial management is designed to reveal both insights and opportunities. Building upon a background of National Account Management, Commercial Banking, Brokerage Services, and Senior-Level Financial Consulting, I draw upon a wealth of practical, first-hand experience to benefit clients in the ways that matter most: A broad-based understanding of business finance that achieves defined, sustainable goals.
