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.
