What reviewers mention most
“Excellent working relationship, once we got to the point where we understood each other”
Our experience with IT Extension on the Seat Reservation project went so well that we've brought them on for two additional projects since then, with a third in the pipeline. At this point, they feel like an extension of our in-house dev team rather than an external vendor.
