Developer Velocity
By replacing rigid legacy code with modern microservices, our engineering teams deploy new features faster, reducing time-to-market.

WHAT WE DO

Our Customer Experience and Onboarding Services

Strangler Fig Pattern Implementation

We incrementally replace legacy monolithic functions with modern microservices. This avoids risks by wrapping legacy OBP and FlexCube systems in high-performance Golang layers.

SOAP/XML to gRPC/REST Conversion

We modernize the communication protocol of your core. Our centralized OBP Proxy Service handles complex XML transformations, exposing clean REST APIs for frontends and gRPC for internal services.

Multi-Tier Redis Caching

We implement intelligent caching strategies with optimized TTLs. This reduces the load on the core banking system by serving frequently accessed data directly from high-speed memory.

Traffic Shadowing and Verification

Before going live, we use traffic shadowing to test new services with real-world production data. This validates performance and logic without affecting the live user experience.

Connection Pooling Optimization

We re-engineer how your application interacts with the core database, preventing connection exhaustion and ensuring stable performance during peak transaction periods.

Independent Service Scaling

By containerizing modernized functions with Kubernetes, we allow individual banking modules (like Payments or Ledgers) to scale independently based on demand.

What You Need to Know

FAQs About Our Core Banking Modernization Service

The Strangler Fig Pattern is an incremental migration approach where new services are built alongside the existing system rather than replacing it all at once. Each new microservice takes ownership of one domain, account queries, transaction lookups, and balance checks, while the legacy system continues handling everything else. Over time, the legacy system's responsibilities shrink until it is either fully replaced or isolated to a minimal footprint. In core banking, this approach is used because a big-bang replacement requires a cutover window where the system is unavailable. For a bank processing live transactions, that window is not acceptable.
