Twelve Foot Guru worked with us pretty consistently for over a year. They really knew the ExtJS framework well, including appropriate and recommended techniques and related complementary technologies.
We were new to ExtJS, and we found it daunting to learn the framework, layout the project, and get started in the right way. The architect-level developers at Twelve Foot Guru were able to do this efficiently for us, giving use confidence that we were building on a good foundation.
Also, when new, challenging requirements came up in the project, they efficiently guided us over the difficulties of selecting and integrating complementary technologies.
Great work, Bryan and John.
