Case Study
Core Banking Cross-Platform Migration
Completed a core-banking cross-platform migration without source code and coordinated integration and performance testing.
Business Context
A core-banking application required cross-platform migration to support continued operation, integration and ongoing maintenance.
Constraints & Challenges
Source code was unavailable, while compatibility, system dependencies, integration and performance risks still had to be addressed.
My Role
Responsible for technical delivery, solution confirmation, test coordination, risk judgement and cross-team issue handling.
Technical Judgement
Used observable behaviour, dependencies, interfaces and testing evidence to understand the system rather than treating unverifiable assumptions as conclusions.
Actions Taken
Analysed system constraints and dependencies, completed the cross-platform migration, and coordinated integration and performance testing.
Publicly Shareable Evidence
The migration was completed with integration and performance testing evidence.
Business Value
Supported continued operation of a critical application, reduced ongoing maintenance cost and improved long-term maintainability.
