ARCHITECT /team lead
A senior Ruby on Rails backend architect.
I specialize in developing back-end heavy applications which process a lot of data and require very complex architecture. I pride myself in an ability to see the bigger picture and effortlessly plan and create large web applications. I have been involved in a variety of innovative projects ranging from eCommerce solutions to mobile social games to copyright management platforms.
Working for my clients I value open communications and clear goals. I like to work in a team and have a lot of experience in doing code reviews and controlling the overall flow of the project.
