01 / Challenge

The Problem

The bank operated on a legacy core banking system from 2004 incompatible with modern payment networks and OJK regulatory reporting. Manual reconciliation consumed 15+ hours weekly.

02 / Solution

What We Built

We built a middleware integration layer using RESTful APIs and ISO 8583 translation to bridge the legacy core to BI-FAST, GPN, and SNAP. A real-time OJK reporting module and mobile banking frontend were delivered without replacing the core system.

03 / Results

The Outcomes

The bank launched mobile banking within 6 months, onboarding 12,000 new digital customers in Q1. Reconciliation dropped from 15 hours to 45 minutes. OJK reporting became fully automated with zero errors.

"Asiateknologi let us compete with digital banks without ripping out our core system. ROI exceeded projections."
