Developers from Zappa did a great job! As in any project, we managed to implement something (and even better than it was planned), we had to give up something in the work process, but it is very nice that the guys always offered their solutions to any problem. I definitely recommend Zappa as very experienced and attentive developers and reliable partners.

Crt Mrzlikar
CNJ Agency, Project Manager

We have been using Zappa for over a year. They are extremely professional and conduct significant research before starting each assignment. This methodical approach to software development results in a better overall product instead of a constant back and forth in the middle of an assignment and undue costs and overages. I would highly recommend them to anyone who is looking to develop any type of complex application.
