Project overview

Client: G2A.comSector: gaming / e-commerce / marketplaceModel:IT outsourcingArea: design system / React / UI components

Edge One Solutions supported G2A.com by providing IT specialists responsible for developing a scalable design system for a global marketplace.

The project included creating reusable UI components in React, documenting them in Storybook, and working on WCAG accessibility, responsiveness, performance, and visual consistency of the platform.

Challenge
G2A.com needed a comprehensive and scalable design system for a global marketplace serving more than 30 million users across 180 countries.

The key challenge was to develop reusable UI components in React using Tailwind CSS, supporting the dynamic growth of the platform and making components easy to implement across different parts of the application.

The solution had to meet WCAG accessibility requirements, work responsively, support high application performance, and be well documented for frontend teams.
Scope of work by Edge One Solutions
Edge One Solutions supported G2A.com by providing IT specialists responsible for developing the design system and UI component library.

The scope of support included creating components in React, working with Tailwind CSS, adapting components to accessibility and responsiveness requirements, and preparing documentation in Storybook.

The team also supported code optimization for testability, UX/UI standards, application performance, and easier integration of new features by other development teams.
Rozwiązanie
W ramach projektu rozwijana jest skalowalna biblioteka komponentów UI w React, zbudowana z wykorzystaniem Tailwind CSS.

Biblioteka obejmuje zarówno podstawowe elementy interfejsu, takie jak przyciski i pola formularzy, jak również bardziej zaawansowane komponenty, m.in. okna modalne i karty produktów.

Komponenty są dokumentowane w Storybooku, co ułatwia ich ponowne wykorzystanie, wspiera spójność wizualną aplikacji i skraca czas integracji nowych funkcji w różnych częściach platformy.
Project significance for marketplaces and design systems
In large marketplace platforms, a design system is not only a set of visual guidelines, but also a technical foundation for fast, consistent, and predictable product development.

The G2A.com project shows how a UI component library can support platform scaling, frontend workflow automation, interface accessibility, and a consistent user experience.

For companies developing global digital products, similar solutions can shorten the time needed to launch new features, reduce interface inconsistencies, and improve collaboration between product and technology teams.
