Technical Skills
PHP
Experienced, 5 Years
Coding in PHP since 2005. Started commercially around 2011 by creating custom advertisement system for client in Slovakia. PHP development is what makes my living. Usually coding with frameworks such as Laravel or Symfony.
JavaScript
Advanced, 3 Years
I like JavaScript as a language, however it must be written very carefully in order to prevent callback hell in bigger codebases. Also used JQuery extensively, mainly its AJAX component.
Node.js
Intermediate, 1 Year
Node.js is awesome for quick I/O operations. I have experienced it in huge, production codebases and boy, was it hell (viz. problem with JS above). Experience with Express.js, Hatch.js, Mongoose and many other libs.

Intermediate
While I have no commercial experience with Java, I have created several desktop systems as part of my degree. Active development of Android applications (links coming soon).
