Top Custom Software Development Companies

Mobile App Development for Application Company

Our level of communication depends on the project. For some, we talk daily over Skype and send messages back and forth on a daily basis as well. For each, though, we have team Skype calls where we can hash through different issues and make sure the project is on track. Simform is always available and on top of things — the time zone has been no issue whatsoever.

Staff Augmentation for Software Company

Their personalities align better to the US culture. I’ve used Eastern European and Indian vendors before and have consistently had problems because of the cultural differences. In South America, a lot of the developers are more independent and line up with our culture better; they push back and ask a lot more questions. BairesDev is really pleasant to work with, overall.

AWS & Mobile App Dev for Sports Trading Platform

BairesDev puts a lot of focus and attention into finding the right relationships for a project. That’s important because it’s not just a working relationship at that point but rather a personal engagement. So, it’s far more rewarding when that interpersonal element is there. I know their team well enough that we know what each other is thinking.

They’ve done the latter very well, helping me open my eyes and remove the bias I had about the project before engaging with them.

The design phase and the autonomy in the build phase were very impressive. The design phase was highly iterative and led to great hifis that reflected our understanding of our user's needs.

We also have Google video calls every day.
