The client faced significant challenges integrating multiple legacy and modern systems, each with distinct interface patterns and communication protocols. This diversity led to fragmented workflows, inconsistent data handling, and increased interdependencies across teams. The lack of standardized integration frameworks made it difficult to streamline development and testing efforts, often resulting in prolonged timelines, redundant work, and escalated project risks. Effective project management became increasingly difficult, requiring meticulous planning, precise coordination, and continuous optimization to ensure seamless interoperability, minimize disruptions, and maintain overall solution quality.
