Daniel Vartanov

Experienced Ruby backend developer


Swansea, United Kingdom


For last five years I've been participating in and leading the development of several large Ruby projects (not only web-oriented). I deeply know Rails and Merb internal code. I participate in Ruby community and often contribute to famous projects, such as Cucumber, Watir, etc. See my profile at a github: http://github.com/DanielVartanov I passionately adopt ideas of agile development and successfully completed several enterprise projects using these techniques. Before programming in Ruby I participated in development of enterprise solutions (used Java, C++). I have major in mathematics and computer science, therefore, I can apply effective algorithms with the maximal simplicity of code.
