   • Lead structured knowledge transfer from the vendor through code walkthroughs, shadowing and reverse-shadowing.
   • Confirm internal team readiness for each platform area.
   • Review and approve vendor deliverables, including code, configurations, designs and runbooks, for quality, maintainability and compliance with Bank standards before acceptance.
   • Identify and close vendor dependencies, including undocumented configurations, custom components, licences, subscriptions and access credentials.
4. Platform Architecture and Operations
   • Own the platform deployment architecture across development, test, UAT, production and disaster recovery environments using virtual machines and containers such as Docker and Kubernetes.
