I’m very experienced software developer. During my career, I’ve been doing many different software development tasks. Last years I have been developing web-based change measuring service on Ruby on Rails. Mostly I have been doing back-end development there, but also some front-end changes.

Photography is my main hobby on my free time.


People are in the core of every change, therefore it is crucial to know how people feel about each change situation. And it is impossible to know if the desired change actually happened without reliably measuring the impact of the change, therefore I want to develop the leading change measuring service, Celkee Insight.


My key areas of expertise are:

  • Web-programming with Ruby on Rails
  • Security
  • C/C++ programming
  • Internet protocols
