Over six months, contributed to Maua-Dev/port_mss_action and related repositories by building robust backend infrastructure for data export, reporting, and access control. Developed features such as historical project data retrieval, Excel export workflows, and secure S3 hosting, leveraging Python, AWS Lambda, and CloudFormation. Improved deployment reliability through CI/CD enhancements and Infrastructure as Code modernization, while strengthening authentication with AWS Cognito integration. Addressed critical bugs in DynamoDB pagination, access control, and configuration management, ensuring stable releases and consistent environments. Emphasized modular, testable code and clear documentation, enabling maintainable solutions for data processing, cloud storage, and automated reporting across environments.
October 2025: Focused on authorization hardening in Maua-Dev/port_mss_action. Delivered a critical fix to the Get All Projects use case that aligns access rules with the intended policy, reducing risk of improper access for non-admin users. This month did not include new feature work outside the scope of bug fixes, but the security posture and policy clarity improved significantly.

May 2025: Key deliverables and impact across Maua-Dev repositories. Key features delivered: - Member Reports Hosting (S3 + CloudFront): Created a versioned S3 bucket with public access blocking and a CloudFront distribution to securely serve member reports content, improving delivery performance and security. - Lambda Layers for Data Processing (Pandas/XlsxWriter): Added Pandas and XlsxWriter Lambda layers and configuration updates to enable cross-function data processing and automated report generation, reducing maintenance friction across Lambda functions and EventBridge workflows. - CI/CD workflow improvements for reservation_front: Standardized stage naming by switching to environment variables (STACK_NAME, VITE_STAGE, GITHUB_REF_NAME, CloudFront ID, S3 bucket names), improving deployment consistency across environments. Major bugs fixed: - DynamoDB Action Pagination robustness: Fixed while loop and ExclusiveStartKey handling to ensure all items are retrieved from actions database. - Download Members Sender reliability & import fixes: Improved error handling and response structure; corrected module imports and parameter naming for the extractor. - CloudFormation output key retrieval bug: Removed hyphens from output keys used to fetch CloudFront IDs and S3 bucket names, ensuring accurate deployment value retrieval. Overall impact and accomplishments: - Increased reliability and scalability of reporting infrastructure, faster time-to-delivery for member reports, and safer, more consistent deployments across environments. - Reduced runtime errors due to improved error handling, robust pagination, and consistent configuration management. Technologies/skills demonstrated: - AWS: S3, CloudFront, DynamoDB, Lambda (Layers), EventBridge, CloudFormation. - CI/CD: GitHub Actions with environment-variable-driven deployment steps. - Programming: Python data processing with Pandas and XlsxWriter; code hygiene with imports and naming conventions.
