Jack of all trades (master of some)

For years RoR is my tool of choice. I use it in many projects including uncommon things like production of DRM protected books on virtual machines farm. 

Developed and leaded multiple projects on ruby/ruby on rails including:

Angular is my current web framework of choice. I am using it in everyday development and teach other developers how to use it.

I am my own system administrator through all my career. Ready to help you with getting things work.
