CD (Continuous Delivery)

Automation is our goal.

TDD (Test Driven Development)

Our target is to build scalable web apps from the beginning. Most of the developers you will find will type code without testing, making the app unscalable and hard to maintain in the near future. TDD is a methodology that we use and allows us to write tests from the beginning of the project, this way every line of the code will be tested.
