Using their expertise they were able to give us invaluable advices and whatever they said was done was really done, with only few really minor defects. Working with Qualifast was definitely the right choice.

    Working with Qualifast was really satisfactory – they got into the project’s requirements fast and were collaborative for all the changes and tweaks we needed in the course of the implementation. I was really impressed with their professionalism – from project plan definition, to abiding to it afterwards and the speed with which they delivered the final product.
