Sumerge partnered with the client to modernize its core platform, replacing tightly coupled legacy systems with an API-first, event-driven architecture. The programme was delivered in phases to keep critical services running, with automated testing and CI/CD pipelines introduced from day one. The result is a scalable foundation that shortens time-to-market for new products, improves reliability across channels, and gives teams the data they need to make faster, better decisions for their customers.
