Crezever-Rebuilding an E-commerce Aggregator Platform for Speed and Performance
Crezever is an e-commerce vendor aggregator platform that brings multiple vendors together in one digital marketplace. When its existing platform started taking approximately 22 seconds to load, performance became a major challenge. Olivia Tech rebuilt the web application and mobile app from scratch, reducing the reported loading time to just 2 seconds. Beyond the rebuild, we continue to improve the platform to deliver a faster, smoother and more efficient digital experience.
The challenge
Crezever Rebuilding an E-commerce Aggregator Platform for Speed and Performance The Challenge Crezever is an e-commerce vendor aggregator platform that brings multiple vendors together in one digital marketplace, enabling customers to explore products and shop through a unified platform. As the platform evolved, performance became a major concern. The existing system was taking approximately 22 seconds to load, creating a frustrating experience for users and affecting the overall responsiveness of the platform. For an e-commerce platform, where users expect smooth browsing and quick interactions, such delays can become a significant barrier to engagement. Rather than continuing with temporary fixes, Crezever needed a stronger digital foundation that could support a faster and more efficient experience. The challenge was clear: How could we transform an underperforming platform into a faster, more responsive and reliable digital marketplace?
What we built
Olivia Tech undertook a complete rebuild of the Crezever platform from scratch, covering both its web application and mobile app. Instead of simply optimizing the existing system, we focused on rebuilding the product with performance and continuous improvement at its core. Key areas of work included: Complete Platform Rebuild: Rebuilt the existing platform from scratch to establish a stronger technical foundation. Web Application Development: Developed a faster and more responsive web experience for the e-commerce marketplace. Mobile App Development: Rebuilt the mobile application as part of the broader platform transformation. Performance Optimization: Focused on reducing loading times and improving overall platform responsiveness. Continuous Product Improvement: Continued refining and enhancing the platform to support evolving requirements and deliver a better user experience. Our approach went beyond delivering a rebuilt product. It focused on creating a platform that could continue to evolve.
The outcome
The complete rebuild delivered a significant improvement in platform performance. 22 Seconds to 2 Seconds: Reduced the reported platform loading time from approximately 22 seconds to just 2 seconds. ~91% Reduction in Loading Time: Achieved an approximately 91% reduction in loading time. Improved User Experience: Made accessing and interacting with the platform considerably faster. Modernized Digital Foundation: Replaced the previous system with a newly rebuilt web application and mobile app. Continuous Improvements: Established an ongoing development approach to keep improving platform performance and functionality. The Takeaway Sometimes, improving a digital product means going back to the foundation and rebuilding it the right way. At Olivia Tech, we don't just develop digital products. We build, rebuild and continuously improve technology to help businesses deliver better experiences and achieve real business impact.
