US Digital Commerce Marketplace

Partnership & scope

LG Electronics US needed a modern digital commerce stack that could evolve storefront experiences without blocking the core catalog and checkout systems. Alpinist partnered on the next-generation marketplace: experience layers in Next.js, a Turbo-managed monorepo for shared packages and design tokens, and Java and Magento services for commerce primitives.

Micro-frontend architecture

The architecture centers on micro-frontend federation—independently deployable surfaces for merchandising, product detail, cart, and content—with explicit contracts for routing, authentication, and API boundaries.

Package sync across teams was a first-class concern: version alignment, shared component libraries, and CI gates so federated apps do not drift during parallel development.

Platform & cloud delivery

Backend work spans microservice applications on AWS for catalog, pricing, inventory handoffs, and operational tooling. Challenges included federated navigation, cache invalidation across MFE boundaries, and keeping staging environments representative of production federation graphs.

Outcomes

The result is a platform teams can extend in parallel—new storefront modules ship without rewiring the entire US site, while commerce integrity stays anchored in proven Magento and Java services.
