Case Study: Azure Cloud Transformation & Service-Oriented Architecture Implementation

The project aimed to modernise the client's IT architecture by transitioning from a monolithic structure to a service-oriented, event-driven design. This required technical design, delivery, and continuous improvement of Azure cloud-based applications, as well as business analysis and delivery management across financial and HR systems.

Our team provided a full scrum team with .NET developers and testing resources, supported DevOps operations, and oversaw the architectural overhaul. Key achievements included optimising Azure cloud applications, delivering large-scale changes to financial and HR systems, and successfully implementing a modular, scalable architecture.

This resulted in improved delivery efficiency, enhanced cloud system performance, and better cross-departmental collaboration.
