The Legacy Challenge

80% of financial institutions in Latin America still run critical processes on systems built before the internet existed. COBOL on AS/400. FoxPro databases. Batch processes that run overnight.

The problem isn't that these systems don't work—they do, reliably. The problem is they can't participate in the real-time, API-first, AI-enhanced world that modern regulation demands.

Our Approach: Bridge, Don't Burn

We don't recommend rip-and-replace. Instead, we create intelligent bridges that let legacy systems participate in modern architectures while preserving decades of battle-tested business logic.

🔄

COBOL to Modern APIs

We create bridge layers that expose legacy COBOL systems as RESTful APIs without rewriting core business logic.

📊

AS/400 Data Liberation

Extract data from DB2/400 and replicate to modern PostgreSQL databases with real-time CDC pipelines.

🔌

Event Streaming Integration

Wrap batch processes with Kafka producers to enable event-driven architectures.

🛡️

Zero-Downtime Migration

Strangler fig pattern implementation with traffic shadowing for risk-free transitions.
