Report
I haven't even received my quote yet and I can already tell I look forward to hiring them. As a Contractor, we've dealt with many engineers over the last several years. All of them have been great, but I'm extremely impressed with Callidus' response times, professionalism and attention to details so far. So much so, I decided to write a review.
