Personal project designs. Very very competent people working side by side. Communication was very easy going and fun 😁. They dedicate a lot of time on video consulting, in details throughout the process. They give feedback on the spot, right away. Fast improvements. Did it for half the time that it was required...Overall 10/10 😁
