PROFILE
I'm a passionate geek and an experienced full stack developer with more than 10
years of code craTing. I love neat soluUons for both high scale infrastructures, big
fishes in the industry as well as small MVPs which has to be great, shiny and be
ready for "yesterday". During last 5 years Ruby was my naUve language and Ruby
on Rails was my best friend along with Git, Bootstrap, AngularJS and EmberJS
fellows. During my adventure as a developer I also was a BOFH (*now known as
DevOp, previously as SysAdmin) so I enjoy providing scalable soluUons for
running the code I write. During my 10 years adventure I've learned how to
effecUvely manage my Ume (it was not so obvious at the beginning aTer all) and
that being agile is a key to both mine and yours happiness.
