I originally just used their premium support so I could send them snippets and get some advice. While even on their public forum for Webix they provide pretty good support... I am a bit inpatient and being able to email someone and hear back usually in a couple of hours was worth the small investment. Eventually I started sending them small projects/ prototypes I wanted to build for my lab, but didn't have the time. The quality of the work was great, and I have used these to speed up my research/project development.
Also even though the team obviously has a ton of experience with the WEBIX framework, some of my more recent projects have not been all HTML/CSS based, and they seem quite familiar with other popular technologies (Docker/Mongo/Python/etc). which has been very helpful...
What do you like most about the company?
Fast, efficient, communicate well, clean code
What they should improve on?
Be better at reading my mind. :-) I tend to throw things at them pretty quick.. surprisingly they are usually able to keep up.
