We've had three attempts at a build with different coding outfits, and this third actually works. I had seen high quality of code from chief coder, and trusted his architecture for this third build

They delivered within budget, project management superb, and they worked out all of the background coding architecture decisions. We did not have a CTO, so this was essential. The web-app needs to be secure, fast enough to compete with FB, and scale.

My project was their project, and they really cared for its success.Â
Are there any areas for improvement or something they could have done differently?
They are superb.
