The Challenge
What We Were Asked to Solve
Legacy mainframe-based core banking system serving 5M+ customers across 8 countries was causing $12M annual maintenance costs. The system couldn't support mobile banking, API banking, or rapid product launches. Digital banking competitors were acquiring customers at 5x the rate.
Our Solution
How We Solved It
Phased modernization: first extracting business logic into cloud microservices while keeping mainframe as record-of-truth, then progressively migrating customer-facing features. New React/Next.js digital banking frontend, Node.js API layer, event-driven architecture with Kafka, and Azure cloud infrastructure.
