Worked on the aws-samples/amazon-bedrock-samples repository to deliver secure, scalable Retrieval-Augmented Generation (RAG) features and deployment improvements. Implemented PII redaction before knowledge base ingestion using AWS Comprehend and Macie, and enforced role-based access control for data retrieval, enhancing privacy and governance. Improved deployment by consolidating scripts, refining CDK-based resource naming, and updating documentation for maintainability. Enhanced the Streamlit UI with better session state management and expanded guardrails, ensuring reliable user experiences across scenarios. Leveraged Python, AWS CDK, and Shell scripting to build cloud-native solutions focused on security, infrastructure as code, and robust backend and UI development practices.
