LAZURIT: Core Web Vitals in the green zone for a store with 1M+ MAU
A federal furniture retailer with a million monthly visitors: how a team of six frontend developers brought the platform's speed into the green zone, built a design system, and made builds 70% faster.
The challenge
An e-commerce platform with 1M+ monthly visitors was hitting a speed wall: Core Web Vitals failed Google's thresholds, hurting both search rankings and conversion. Meanwhile the team struggled with slow builds and inconsistent UI across sections.
What was done
- Led a team of 6 frontend developers: planning, code review, mentoring, and process building.
- Optimized Core Web Vitals into the green zone: LCP, CLS and responsiveness work on real platform traffic.
- Storybook design system: a single component library replacing inconsistency — new pages assemble from ready blocks.
- Build migration to Vite: build time cut by 70%, faster development and deployment cycles for the whole team.
- CI/CD with automated tests: every change is verified before production — regressions are caught before users see them.
The result
Platform speed is in the Core Web Vitals green zone with 70% faster loading. The team ships on a unified design system with fast builds and automated tests: new features reach production faster and more reliably. The site is live at lazurit.com.
