In a few months, a supply engineering team was created. Thus, our developers became fully valid members of the project. We focused on building and modifying the functionality for buyers. The biggest technical challenge our software development team had was related to the legacy code that we had to optimize and rewrite. Our development team was responsible for improving this workflow. The aim was to improve the conversion rate so that sellers do not leave the website during the ordering process. To be more specific, we remade the filling form, which was very cumbersome and complicated. We reduced the number of steps users should take to make the form more convenient and user-friendly.
