Challenges We Faced

A regional telecommunications provider relied on a mission-critical legacy application that struggled to support rapid subscriber growth.

The organization faced multiple challenges:

  • Frequent downtime disrupting customer services and internal operations
  • Performance bottlenecks during peak usage affecting service activation and support
  • High technical debt from years of patch-based fixes
  • Limited scalability due to a rigid monolithic architecture
  • Poor documentation increasing dependency and troubleshooting risks
  • Rising operational costs driven by ongoing maintenance demands

The telecom provider needed a stable, scalable, and high-performance application platform without disrupting live network operations.
