    I think that only hard work, positive attitude towards new challenges and hunger for knowledge can make you an expert developer, that's why I've been constantly broadening my programming skills. Ruby on Rails became my great passion about a year ago and since then I've worked on a couple of projects. I also have experience with CSS, Git, HTML/DHTML, JS, MySQL, Smarty, SQLite, UML, MVC and more. Look forward to working on your projects! :)  less

    Software development is not only my profession but also my greatest passion and hobby. This is why I spend majority of my free time improving my programming skills, learning new concepts, technologies, languages and tools. I get the greatest satisfaction when products I develop are released to the world and people start using it - that makes me want to spend more time at work. When not in front of my monitor, I'm probably taking care of my daughter or doing some sports (tennis and swimming most of the time).  less

    While I've been working in the company, I was engaged in prototyping of portals and internet-banks. I’ve been involved as Front-end developer on this projects. I have developed user interfaces with cross-browser compatibility, using Javascript, frameworks such as jQuery and Ajax technologies. Front-end was built on X(HTML) + JS and as a backend Ruby on rails or Java, XSLT stack was used. I have abstract mindset and can easily “hack” through others user-interface code. User interfaces, in, practically, all projects, were done, using Ajax, so I got much expertise with maintaining Ajax software. After a year of working in the company, I’ve got two juniors as a mentor. Also I have developed a highly dynamic HTML/JS prototype of an internet-bank, communicating with the customer and rapidly adopting changes under heavy pressure from client. Recently I got highly involved in studying client-side MVC libraries such as Backbone.js.  less
