As the sole designer and developer, I was tasked with creating a comprehensive B2B platform for Petrokov. The goal was to enhance the user experience for construction companies managing product purchases and pricing for their own clients. A key challenge these companies faced was managing their discounts while maintaining profitability, requiring a streamlined solution to optimize the process. With this project, I built the entire platform from the ground up, from user research to the final implementation, including a robust design system, search functionality, and intuitive UI/UX design.
