E-commerce Lego Website migration
LEGO.me was originally built using Angular and faced performance and scalability limitations. I joined the team to lead a full frontend migration to Next.js with React, enabling a more modern development workflow, faster performance, and a smoother user experience across international markets.
Outgrowing Angular: The Need for Change
The existing Angular codebase limited performance and made global rollouts complex. With growing performance expectations and SEO needs, LEGO required a modern, maintainable architecture to support its next phase of digital growth.
Building a Faster Future for LEGO.me
As part of the team worked in EPAM for the MAF Client, I participated in migration LEGO.me from Angular to Next.js — dramatically improving performance, maintainability, and development speed. This was more than just a framework swap — it was a modern frontend rebuild aligned with business goals.
Next.js to the Rescue
Using Next.js and React, together with team, we rebuilt the entire frontend layer with SSR and SSG support, significantly improving load times and Core Web Vitals scores. The new architecture enables faster development, modular component reuse, and lightning-fast page rendering.
What Made This Project a Success
Migrating LEGO.me wasn’t just about new tech — it was about creating a faster, cleaner, and more future-proof digital platform. Here’s what made this project stand out and how it brought real impact to users and the business.
