The client is a European marketplace of household goods. The company sells unique household goods, enabling its users to act as a seller, buyers, and communicate on its platform.


The client had a need to scale and improve their site. In order to compete in the market, they were providing users with an app with unique and necessary functions for the convenient purchase and sale of goods. The most important improvements were to be:

  • an upgraded platform with additional features for the sale and purchase of goods;

  • the ability to save favorite products, their quick search and viewing;

During the development of the task, our team proposed many different steps to implement the final idea of the client. As a result, we’ve managed to carry out a qualitative revision and justify the credibility of our client. To embody the agreed solutions, we have:

  • created an intuitive interface based on the design in Figma;
  • redesigned the code to improve the performance of the app;
  • delimited the code to enhance the performance and maintenance of the app;
  • carried out the transfer of native components from iOS to Android
  • expanded functionality and opportunities for users by introducing tools such as product filter, categories, convenient search, etc.;
  • developed a chat inside the software for convenient communication between users.
