Transformation Overview
The Group, Hungary’s largest financial services provider and a leading banking entity across Central and Eastern Europe, executed an enterprise-wide modernization to transition from legacy, monolithic constraints to a cloud-native architecture. By implementing the eMACH.ai Core Banking platform, the Bank replaced its two-decade-old mainframe stack with an API-first, event-driven ecosystem.
Despite the challenges of a nearly 20-year-old legacy system slowing product innovation, success was ensured through a structured progressive modernization that mitigated the risk of mass migration. This transformation enables the Bank to serve 17 million customers across 11 countries with millisecond-grade processing, ensuring balance integrity and 24*7 availability across all digital and branch channels.
