My experience with Zlatko was %1000 positive.
His response to my questions were always quick. We exchanged up to 15 emails a day.
His knowledge of WordPress is exceptional. His on-page SEO of my site was flawless. He went beyond just doing the basic and moving on. He showed a personal interest my project.
I have worked with a lot of freelancers on odesk. Zlatko has been the best.
