Dimitar Kakalov
General Manager at LanguageBox.co
Petio developed the site www.WorldStoneFair.com which I am currently managing. It is a dynamic web page following complicated logic. I was impressed that Petio is not just very good developer but also (even more important) a person that may provide with appropriate solutions. During the development we passed through critical stages but I was confident that Petio will find the way within such complicated network of functionalities. Moreover, he even suggested lots of new functionalities that I haven't thought about and that eventually found place in the whole logic of this page. I would like to highly recommend Petio to anybody who needs IT professional or consultant at his team or for freelance projects.
