Wayfair

MILL5 partnered with Wayfair across multiple teams, including the Visualization and Control (VAC) team and the Supplier Integration Group, to modernize user interfaces, migrate critical applications to Google Cloud Platform (GCP), and build high-performance microservice APIs. The engagement focused on improving pricing systems, supplier integrations, and cloud scalability to support extreme traffic demands during peak retail events.
