      4.5 ★

      Software Development Review from Marcos Queiroz

      They were very responsive and the quality of the work was good. We experienced a few challenges with the back and forth during deliveries and some unexpected delays but they were always receptive to feedback and responded well to our concerns. I'd happily recommend them, especially Megha as the Project Manager and Savan as the Developer.

      Walter was a great help with our wifi issues! I am not an IT person and he was able to work with my limited knowledge on the current issues and find a solution along with multiple follow-ups to ensure everything is working perfectly. Thank you!
