Key Challenges
- Harmonize and stabilize a high volume e‑commerce site
- Optimize the platform continuously without losing sight of performance
- Collaborate internationally and set up a PWA solution
UX and UI optimization as a seal of performance
Our designers initially focused on improving the UX and UI interface in order to optimize the presentation of items and facilitate the steps in the purchase journey.
At the same time, new functionalities were developed, allowing products and promotions to be presented in an optimal way.

Add-on integration to improve the customer experience
Many tools have been integrated like: BazaarVoice to improve reviews and reduce hesitation, Wunderkind for the conversion rate and analyze the customer journey, Zendesk to improve customer engagement and loyalty or even Klarna for deferred payments.
All in the name of great customer experience.


PWA as a driver of performance
The development of the international PWA platform allowed us to create a native and natural browsing experience, close to that of mobile applications, and ideal for optimizing the journey and the user experience.
Loading speed is now almost instantaneous across the site. Thanks to a lot of collaborative work, we have pushed the limits of existing technologies and created a performance-oriented e‑commerce platform.
