Hello there! We have installed whatsapp to answer your questions 24/24 & 7/7... So feel free to use it.
I'd like to share my experience regarding the collaboration we had and still have with Ergonomic.
First and foremost, their structure makes you define exactly what you need with a precise website's architecture. This key step is usually forgotten in other web-designer companies because they expect you to come with the structure and simply design it. With Ergonomic I shared my experience with Djihed, and we exchanged until we (me as a professional in my sector and him putting himself in a random costumer's skin) found the perfect architecture to be handy and costumer friendly.
After that, the process in on the way and the feedback exchanged helped to reach our goal (efficience - visual - professional). Quickly, Charles and his dev team understood the direction we wanted to go to. We were pleased to collaborate with them and plan in a near future to dev the version 2 of our website.
It was a essential part of the growth and success we have today!
