Technical Skills



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.



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.



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.


Java (Android)


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).




University experience (no commercial). Academic level knowledge of syntax, .NET, MVC, EF, web services and some more. Created windows form applications and distributed systems using C# as part of my software engineering degree.


University of Greenwich
