A multinational bank was running its core operations on 50+ aging applications — expensive to operate, slow to change, and increasingly hard to keep compliant. Every previous modernization attempt had stalled on the fear of downtime.
We ran a strangler-fig migration: wrapping legacy systems in APIs, carving out services one by one to cloud-native microservices, and staging every cutover behind feature flags with instant rollback. Compliance controls were built into the platform, not bolted on.
All 50+ applications reached the cloud with zero downtime. Operational costs dropped 60%, performance tripled, and release cycles went from quarterly to weekly — with a cleaner audit story than the legacy estate ever had.
“They did the thing every vendor promised and none delivered: modernized the core without a single minute of downtime.”
