Walmart, one of the world's largest retailers, operates thousands of stores and processes millions of transactions daily. To support its digital transformation efforts, Walmart partnered with BAAS to modernize key enterprise systems, enhance operational workflows, and build scalable platforms that improve both customer and employee experience. BAAS provided engineering expertise across application modernization, supply chain optimization, enterprise integrations, data processing, and cloud automation-helping Walmart strengthen reliability and efficiency across its global operations.
Project Overview
Walmart required modernization of multiple digital systems that support retail operations, store management workflows, transaction processing, customer information systems, inventory management, and internal support applications. BAAS delivered end-to-end engineering solutions including backend development, UI/UX enhancements, microservices architecture, cloud deployments, data processing pipelines, and automated testing.
