Overview

The Enterprise Banking Platform modernization initiative involved designing a cloud-native architecture using Infrastructure as Code and secure workload identity. The platform improved scalability, security, and deployment consistency across all production-critical banking systems while maintaining strict regulatory compliance.

Key Features

• Zero-trust architecture with OIDC-based identity federation
• Vault for dynamic secrets rotation and encryption
• SPIFFE/SPIRE workload identity for mTLS between services
• Fully automated IaC with Terraform modular design
• End-to-end observability with centralized logging and alerting
