Summary
Created a reusable IAM Access Analyzer widget for visualizing and managing resource-based security policies across AWS services. The project emerged from DynamoDB's resource-based policies implementation and evolved into a shared component used by multiple AWS service teams.

Problem
Each AWS service team was building their own policy editor implementation, leading to:
- Duplicated Effort: Teams independently developing similar policy editing capabilities
- Inconsistent Experience: Different implementations across services confused customers
- Maintenance Burden: Each team maintaining separate policy validation logic
Goals
- Create a reusable widget for resource-level policy management
- Validate the implementation through DynamoDB's resource policies feature
- Enable adoption by other AWS service teams
Implementation
Approach
- Worked with partner teams (S3, Identity) to understand integration needs
- Designed and prototyped interactions within DynamoDB
- Validated the widget's effectiveness through DynamoDB's resource policies launch

Key Features
- Resource-level policy visualization
- Integrated access analyzer validation
- Service-specific policy customization
