Worked on the cap-js/attachments repository to deliver advanced attachment workflow features and reliability improvements over a two-month period. Built multi-level draft entity associations and nested attachment support using Node.js and JavaScript, introducing a back-association chain builder and deeper nesting handlers to manage complex data relationships. Enhanced error handling and resilience by adding rejection events for uploads, downloads, and size validations, with comprehensive testing to ensure stability. Improved the SAP Malware Scanning Service integration by implementing semaphore-based rate limiting, automatic retry with exponential backoff, and refactoring to axios for better error handling, optimizing throughput and reducing resource contention in backend operations.

Apr 1, 2026April 2026 monthly summary for cap-js/attachments focused on reliability and performance improvements for the SAP Malware Scanning service. Delivered rate limiting and automatic retry to handle HTTP 429, refactored the scanFile flow to axios for improved error handling and retry-after support, and optimized the data path by skipping redundant object-store downloads for SHA-256 calculation when scanning is enabled. These changes reduce failures, improve throughput, and lower resource pressure on shared subaccounts, while improving overall maintainability and deliverability.
