A commerce replatform that lifted conversion without slowing teams
A phased move from a brittle monolith to a composable commerce stack, with measurable gains in release speed, checkout reliability and conversion.
Growth was trapped inside a fragile platform.
The retailer's teams could not test new journeys without risking core checkout. Campaign launches required brittle coordination, and the brand team had limited confidence that digital experiences matched the new identity.
We moved by customer journey, not by system diagram.
Quantlix created a composable front end, API orchestration layer, design system primitives, and checkout observability. The team migrated search, product detail, basket, and checkout in controlled slices.
- Instrumented conversion and reliability before migration.
- Used feature flags for phased traffic movement.
- Aligned design tokens with production components.
The new stack changed how the business shipped.
Marketing gained faster campaign cycles, product teams shipped weekly, and the checkout experience became more resilient. Conversion improved because reliability, performance, and content velocity moved together.
