Case Study: a US Telecom Major modernizes legacy integrations with Netsmartz MuleSoft API migration

US Telecom Major cuts technical debt by 90% with Netsmartz

Netsmartz partnered with a US telecom major to modernize its legacy integration infrastructure. The customer faced significant challenges due to its reliance on outdated Java and SOAP-based systems, which created high technical debt, performance bottlenecks, and limited scalability for digital services.

The solution from Netsmartz involved migrating these legacy integrations to a modern RESTful architecture on the MuleSoft Anypoint Platform using Mule 4. They implemented a three-tier API framework and executed a zero-downtime migration. This project resulted in a 90% reduction in technical debt, an 85% improvement in system maintainability, and a 70% acceleration in integration delivery, all without disrupting service for millions of customers.
