Technical Skills


Experienced, 10+ Years

Coding in PHP since 2005. Started commercially around 2011 by creating custom advertisement systems as a freelancer. Experienced with frameworks such Laravel / Lumen or Symfony however worked also with a lot of large, legacy codebases. Following modern standards such as PHP-FIG and PSRs.


Intermediate, 3 years

Golang is my preferred language for all the new microservices I write. Because it is relatively new and modern language, Google's engineers could create language without ugly legacy issues (looking at you PHP) and the results are amazing!


Experienced, 10 Years

I like JavaScript as a language, however it must be written very carefully in order to prevent callback hell in bigger codebases. As most of the web devs, I started with JQuery somewhere around 2007 (for AJAX mostly). Later moved on to Angular and most recently exploring ReactJS. Evolution of the front-end development field over the past years is fascinating.
