"Retter Heatmaps & Replay"

The client approached us with a clear goal: to address the scalability challenges their existing app was facing. The previous architecture was limiting its potential as user traffic increased, resulting in slowdowns and a reduced ability to support future growth. The app required a full overhaul to:

• Scale effectively: Improve the ability to handle a growing user base.
• Optimize user engagement tracking: Enhance the tracking of user interactions across various store elements like products, collections, and carts.
• Improve performance: Create a more reliable system that could handle increasing data volumes.

To solve these challenges, we conducted a thorough analysis of the existing application and proposed a modernized solution:

• Backend migration: Moved from PHP to Node.js for better scalability.
• Frontend revamp: Rebuilt with React.js and TypeScript for improved responsiveness.
• Database redesign: Optimized with MongoDB and PostgreSQL for scalable data handling.
• Microservices architecture: Transitioned from monolithic to microservices for better performance and flexibility.
• Enhanced tracking: Tracking system redesign for more accurate data collection, faster processing, and better heatmaps and session replays.

The upgraded Retter app now handles growing traffic smoothly, providing faster data processing and clearer insights for merchants. With improved tracking, merchants can optimize user experience and boost conversions. The new architecture ensures long-term scalability, while heatmaps and session replays help businesses make informed decisions to enhance UX and increase sales.
