• Own the end-to-end target architecture for the omni-channel platform, defining architecture principles, guardrails and the phased path from the current state to the target state.
• Assess and reshape the existing microservice architecture, including service boundaries, data ownership, transaction patterns and event-driven architecture, and provide independent recommendations to the vendor.
• Define the target API gateway, integration, configuration and security architecture, including API security, zero-trust principles, stateless architecture, event streaming and caching.
• Develop independent capacity and infrastructure sizing models covering digital channels, UPI and IMPS, and reconcile these against the vendor's estimates.
• Define the platform's migration, resilience and non-functional architecture, covering active-active design, performance, observability, failure handling, rollback and release readiness.
