Selected Systems & Platform Experience

We’ve built, integrated and optimised financial systems where logic matters, performance matters, and mistakes are expensive.

In other words: enterprise-grade, not experimental.

Core Banking & AS400 Integration

Worked with legacy AS400 backend systems powering high-volume financial operations. Designed integration layers and modern APIs to bridge structured legacy logic with modern platforms.

Yes, AS400 still runs serious money. And yes, we speak it's language.

AS400 Integration APIs Core Banking

Spring Boot API Architecture

Designed and built scalable RESTful APIs using Spring Boot to support loan origination, decision engines and mobile clients. Clean architecture, modular services, production-ready deployments.

Loan Origination & Decisioning Systems

Implemented scorecards, rule engines and decision trees for automated lending workflows. Built affordability calculations, offer sequencing logic, and risk-based decision frameworks.

Because “approved” should never be random.

What This Means For You

We don’t just build interfaces. We understand decision engines, compliance constraints, affordability logic, workflow states and integration layers.

That means fewer surprises in production and fewer “why didn’t we think of that?” moments.
