DEVELOPMENT
We fully replaced the technology foundation of an online store, created a new UX/UI and prepared the platform to scale to 1M+ products. After launch, purchase conversion grew from 1.4% to 3%.
STOREinUA is an online store of appliances and electronics with a large product base, complex business logic and integrated services. We rebuilt the platform at the frontend, backend and infrastructure level in two stages: first we replaced the stack while keeping the existing interface, then we integrated the new UX/UI and extra functionality. Throughout, the store kept running and taking orders.
The STOREinUA business outgrew the capabilities of its technology platform. The OpenCart site accumulated technical errors, ran slowly and depended on a large number of plugins and third-party integrations. Through PriceMatrix the system received data on roughly 60 thousand products. Further growth needed a new architecture built for over a million SKUs. The main challenge was to completely rebuild the platform without stopping the store.
Design an architecture for a catalog of 1M+ products and a load of up to 1 million visits a month.
Move business logic, data and integrations to a modern stack while keeping the online store running without interruption.
Update the UX/UI and improve navigation, search, catalog, product page and checkout, reducing the barriers on the way to an order.
We analyzed the existing platform, catalog, PriceMatrix, search, pricing, checkout, personal account and external integrations. We determined which business logic had to be kept, which components had to be rebuilt and which technology limits could be dropped.
A map of business logic, integrations and requirements for the new architecture.
Backend and data: we moved business logic to Laravel 11, separated the API and used PostgreSQL for product data and further catalog scaling. Frontend and infrastructure: we rebuilt the frontend on Nuxt 3, Vue 3 and TypeScript with SSR, separated the system's components and built the infrastructure on AWS and DigitalOcean.
In parallel we rethought the user journey: from navigation and search to the product page, cart and checkout.
After the new technology foundation launched, we moved to the second stage, product transformation. We continued building additional backend functionality, implemented new features and gradually integrated the updated UX/UI. So the new architecture, frontend and business logic merged into one product without having to stop the store.
A fully updated e-commerce platform with a new UX/UI and functionality.
STOREinUA got a new technology foundation, independent frontend and backend, a distributed infrastructure and an updated user experience. The architecture is built for a catalog of over a million products, and the staged migration kept the store running throughout the transformation. After the new platform launched, we recorded growth in conversion and key e-commerce metrics: purchase conversion grew from 1.4% to 3%, purchases by 158.95% and total revenue by 170.51%. The updated interface brings catalog, search, product page, comparison, cart, checkout and personal account into one user experience. Purchase and revenue data: GA4, comparing 1–17 January 2025 with 1–17 January 2024. The growth was recorded after the platform launched; other business factors could also have influenced it. We did not just move StoreinUA to a new technology stack. We rebuilt the foundation of a live e-commerce store, kept sales continuous and created a platform ready for the next stage of business growth. From OpenCart and 60K products to a modern architecture for 1M+ SKUs and a 3% conversion rate.
The team took a professional approach to upgrading site, ensuring high-quality project delivery without interrupting the store’s operations.
