I've had experience of Tim's coding when he started out, always high quality work and clear in communication. He has made the transition to running his coding team by hiring high quality coders and a project manager who is not afraid of asking hard questions. In our case, we wanted a web-app and JSN took on the responsibility of ensuring it works across all platforms and browsers. Superb.
What do you like most about the company?
High quality project management, complete package: they deliver working code.
What they should improve on?
Estimates. A fiendishly hard thing at the best of times. Prioritising what features to build depends on having accurate estimates. Improvements in this would help every startup.
