FIS Global

The Challenge

The existing application was built on .NET Framework 4.5, which had reached end-of-support. In a financial systems environment, this created serious security vulnerabilities, compliance risks, and blocked AI integration capabilities. The legacy UI was outdated. The architecture couldn't be extended without significant risk of breaking existing business workflows. FIS Global needed modernization without disruption.
