The Challenge
The client was operating on a 20-year-old mainframe architecture that could not handle modern real-time transaction volumes. Downtime was costing $50k/minute, and new feature deployment took 6 months.
The Solution
We architected a strangler-pattern migration to a microservices architecture on AWS. Step-by-step, we decoupled the core ledger from the monolithic frontend, replacing it with a high-performance Go-based backend and a React dashboard.
Key Results
400% increase in transaction processing speed
99.999% uptime achieved (vs 92.5% previously)
Deployment cycles reduced from 6 months to 2 weeks
