Tens of thousands of products, one interface – e-commerce for a nationwide chain of electrical wholesalers

The goal was to create a modern, responsive and high-performance user interface for an electrical wholesaler that:

• Makes online shopping quick and convenient on any device.
• Handles a large number of products and an extensive category structure.
• Works with the existing backend and the client's mobile app, “Kwant App”.
• Allows dynamic management of content and the blog.

The main challenge was fitting a modern front end precisely to an existing backend and ready-made mockups, while keeping the interface fast and intuitive and leaving the platform flexible for further development.

Our team designed and built the front end of the online store using the latest web technologies. We worked in weekly sprints with regular meetings with the client's team.

• Frontend: Next.js (React), TypeScript, Material UI - for a fast, accessible and responsive interface.
• CMS: Strapi integrated with ChatGPT - for managing content and automatically generating blog posts.
• Hosting: Vercel - for instant deployments and real-time previews of work in progress.

• Advanced search and product filtering.
• Branch selection with stock level lookup.
• An extensive customer account area for managing accounts.
• “Strefa Pracownika” (Employee Zone) - a dedicated panel for store staff.
• Modules: news, “Akademia Kwant” (Kwant Academy), company information.
• Promotional pages and products with a rewards system.
• A loyalty program for customers
• Account registration for individuals or businesses.

• A complete, responsive store front end delivered in under 6 months.
• Faster delivery of new features thanks to Vercel and CI/CD.
• Automated blog content thanks to the CMS's AI integration.

The front end of the Kwant platform is a great example of effective collaboration between a development team and a client with a clear vision for their product. A carefully planned process, modern technology and close integration with existing systems resulted in a fast, stable and functional online store. The project not only met end users' expectations but also opened the door to further development.
