One of India’s largest nationalized banks, with USD 160 Billion+ in assets, 8,500+ domestic branches, 76,000+ employees, and 9,800+ ATMs, was running its Integrated Cash Management System (ICMS) on a blend of Visual Basic 6.0 and VB.NET technologies.
As regulatory changes, digital payment systems, and customer expectations evolved, the bank required a specialized technology partner to stabilize, support, and future-proof this legacy-heavy, mission-critical system.

- Sprawling in size with over 20 million lines of code
- Used nationwide across all bank branches
- Expected to quickly integrate APIs and adhere to RBI regulatory updates
The complexity demanded deep domain knowledge, banking-specific workflows, and hands-on experience with Microsoft technologies both old and new.
