Bank of Baroda — EWS Migration
India
Early Warning System Migration & Enhancement for Public Sector Bank. ATS led the complete migration to a Spring Boot + Angular architecture on Liferay DXP 7.4, introducing Angular portlets for dynamic UI, a multi-level maker-checker approval workflow, and predictive analytics modules for real-time financial risk flagging.
The challenge
Why this project mattered
Bank of Baroda required modernisation of their existing EWS to handle significantly increased data volumes from post-merger entity integration (following mergers with Vijaya Bank and Dena Bank). The legacy monolithic architecture could not support the scale, and new regulatory requirements mandated enhanced audit trails and maker-checker workflows.

Data integration pipelines were built to ingest data from merged entity systems seamlessly.
