JavaAWSInfrastructure as CodeTypeScript

Owned end-to-end system design and implementation of a cloud-native authentication abstraction layer compliant with OAuth 2.0, authoring design docs with trade-offs and decoupling it from infrastructure dependencies to improve availability, resiliency, and architectural flexibility.
Built and configured an API Gateway with custom domains via Route 53 and ACM to trigger Lambda function, enabling reliable request routing to pod-level endpoints, and defined fine-grained IAM role-based access policies to strictly govern Java client permissions.
Engineered a custom token injection mechanism utilizing Java Reflection to invoke private methods within Amazon’s internal authentication library, overriding the default client auth flow by dynamically injecting middleware-fetched access tokens into HTTP headers.
Provisioned and managed cloud infrastructure via AWS CDK and CloudFormation with TypeScript, integrating CloudWatch for logging, metrics, and observability, as well as CI/CD pipelines for automated deployment.
