Project Summary

e-point SA built and modernized a Digital Experience Platform for Santander Bank Polska, conducting application and business analysis and implementing backend and frontend optimizations. The engagement included hosting and infrastructure upgrades, a frontend rewrite from JavaScript to TypeScript, caching and lazy-loading optimizations, and image format improvements. As a result, the portal saw a 250–300% increase in page speed, a ~10% lift in conversion on selected pages, and a 75% reduction in carbon footprint per page view.

Key Challenges

  • Build an innovative Digital Experience Platform for today's requirements
  • Reduce the loading time of santander.pl pages
  • Stably accommodate twice as much traffic
  • Increase the computing power of application servers

Project Deliverables

  • Caching implementation for frequently accessed data
  • Frontend rewrite from JavaScript to TypeScript
  • Image optimization to WebP format
  • Lazy loading performance optimizations
