Experience
Enhancing Retail Performance with an Advanced Recommendation System
Developed a product recommendation system for a brick-and-mortar food retailer, fundamentally transforming its customer engagement strategy.
I designed robust data pipelines for this project to streamline the extraction, transformation, and loading processes. Utilizing collaborative filtering, I created a recommendation model that dynamically adapts to customer preferences, significantly enhancing the shopping experience. To integrate this solution, I engineered a low-latency API that connects the recommendation model to the retailer's app, ensuring swift and responsive data delivery. The API also included an A/B testing module and comprehensive KPI monitoring capabilities, allowing for real-time performance assessment and optimization.
The system's architecture was planned to withstand the demands of daily operation by over 1,500 sellers, achieving remarkable performance metrics, including sub-200ms latency and exceptional reliability, with zero downtime reported since its deployment. This project has substantially impacted the retailer's business, contributing to a 35% revenue growth per customer by offering personalized shopping experiences and fostering customer loyalty.
