I hired Yannis for the evolution of our website: - Addition of pages according to the existing graphic design. - Implementation of a dynamic data display system via JSON file. - Adjustment of structure and display. - Implementation of technical SEO best practices (tags, structure, basic optimization). - Complete responsive adaptation of new pages (mobile / tablet). - Testing and correction phase before final validation. Yannis showed a perfect initial understanding of the project, communication was fluid and responsive at all times, the project was completed on time, everything was completely satisfactory.

Yaniss is a person with whom I had the pleasure of working for several reasons. He is available, responsive and takes the time to explain diplomatically. He invested himself greatly in my project. His work and the results provided are beyond my expectations. I will call on him again in the near future, that's for sure! I highly recommend his profile, you will not be disappointed! Thank you again Yaniss!
