Project Overview
Bouwkampioen approached us with a clear challenge: their Magento PWA platform had become a barrier to growth. Poor performance, slow development cycles, and technical instability limited both customer experience and expansion opportunities.
We proposed a complete migration to the Hyvä theme. This allowed us to resolve performance issues, redesign the site for a modern and consistent user experience, and lay a stable technical foundation aligned with the client’s growth strategy.
Challenges & Pain Points
- Performance bottlenecks — PWA solution caused sluggish speeds, especially on mobile
- Low conversion experience — Poor loading times led to user frustration and high abandonment
- Technological limitations — PWA architecture restricted automation and slowed down development
- Custom functionality adaptation — Every GraphQL query and module had to be rebuilt for Hyvä compatibility
- Zero disruption — Client required a fully operational store during migration and launch
