Real-World Example
Keyhole partnered with a regional healthcare system to modernize a legacy patient scheduling system built on .NET Framework 3.5 that couldn't integrate with modern EHR platforms.
Our consultants designed a phased migration to .NET Core and cloud-native architecture that maintained 100% uptime throughout the 8-month transition, eliminated $120,000 in annual licensing fees for the legacy system, and reduced appointment booking time from 8 minutes to 90 seconds.
