From monolith to microservices without stopping sales
We moved the Stockholm-born sneaker retailer from a monolith to a microservice platform: a PWA storefront synced with the mobile app and an 18-month phased migration with zero downtime.

What had to
be solved
Peak load
Limited-edition drops brought the monolith down.
Slow change
Every new feature required changes across the whole system.
Web and app
Cart, wishlist and orders had to match on the site and in the app.
No downtime
The move could not stop sales.
What we
did
Audit
Architecture, performance and code of the existing system.
Microservice design
A new ecosystem split into consecutive migration stages.
PWA storefront
A fast storefront that feels like a native app.
Sync with the app
Cart, wishlist and order history are shared between web and mobile.
Personalization
A product recommendation system.
Monitoring
Proactive monitoring in New Relic from day one.
What the client
got
A new platform
Microservices instead of a monolith, without stopping the business.
Ready for drops
Limited releases no longer take the site down.
One experience
Website and app work with the same data.
