Tech migration of a telco application

See how Opcito modernized a telecom security platform by migrating a legacy .NET system to a unified, scalable Java-based ecosystem.

Engagement details

A telecom security provider needed to bring an acquired .NET-based platform into their predominantly Java ecosystem. The mismatch slowed integration, led to uneven maintenance efforts, and made it harder to meet strict compliance and scalability requirements. Opcito led a full modernization program, re-engineering the platform to Java Spring Boot, modularizing critical telecom workflows, upgrading the UI, and establishing automated deployment pipelines. The unified architecture now handles SIM lifecycle operations, usage tracking, MVNO processes, and edge cell orchestration with improved performance, better security alignment, and significantly lower operational friction.
