Case Study: Central African Banking Consortium achieves 10× throughput and 5× faster response times with Teamvoy's banking app refactoring

a Central African banking consortium boosts throughput 10× with Teamvoy

The Central African Banking Consortium, a group of seven banks, faced a critical challenge with their white-label mobile banking app. Despite having over 200,000 users, the application was unstable, suffering from crashes, slow transaction throughput, and a complete lack of monitoring. This performance bottleneck was capping the business's growth ambitions. They engaged Teamvoy for an IT audit, code refactoring, and app performance optimization to stabilize and modernize the platform.

Teamvoy implemented a solution that first stabilized the live app and then executed an incremental refactor. This involved reconstructing undocumented system requirements, modernizing the architecture with encapsulated services and Apache Kafka, and implementing new CI/CD pipelines and monitoring with Sentry. The results were transformative: the app achieved a 10x increase in requests per second and 5x faster response times, while production crashes were eliminated. Notably, Teamvoy's entire refactoring program was funded by reallocating the 30% of the development budget that was previously spent on bug fixes.
