The new version of the online exercise area of the online platform Zanichelli has been released; several months of work, from design to development, which involved all the architecture, frontend and backend, of the online platform which manages over a million exercises. The interface has been entirely designed from a ‘mobile first’ perspective, for a more intuitive and immediate usability. A milestone born from the synergy between developers, systems engineers, product owners and user experience design experts. The preview to try for free is available on ZTE.
