Case Study: a leading Argentine bank modernizes its IVR communication platform with Baufest

Leading Argentine Bank achieves 99% test coverage with Baufest

A leading Argentine bank faced the challenge of modernizing its high-cost, decade-old C++ messaging engine for its IVR system. The legacy application was difficult to maintain and scale, and it required specialized expertise. The bank partnered with Baufest to build a new, scalable communication platform.

Baufest developed a new messaging engine using Akka.NET, leveraging its asynchronous actor-based architecture to create a high-performance platform. This new communication layer now supports the IVR and other digital channels that interact with the bank's core systems. The solution delivered responsive performance under heavy workloads, 99% test coverage for simplified regression testing, and a modern architecture that reduced maintenance cycles and isolated failures to prevent cascading issues.
