Month: 2026-03 Overview: Delivered on-call reliability, scalable message-driven workflows, and user-experience improvements across cozy-stack and cozy-drive. Implemented event-driven user lifecycle operations, hardened message publishing, new authentication workflow capabilities, and batch-oriented file handling to support large datasets while maintaining security and data integrity. Key achievements: - Force deletion workflow via RabbitMQ in cozy-stack with a dedicated deletion route that publishes a user.deletion.requested message; added unit tests covering permissions, email validation, publish failures, and successful publishing. - Established a dedicated RabbitMQ Publisher with its own connection and lifecycle management; added graceful shutdown to prevent TCP leaks. - Added support to toggle two-factor authentication mode via RabbitMQ and propagate updates to user authentication settings. - Implemented recovery email synchronization by handling user.recovery-email.updated messages and persisting changes to instance settings for accurate SaaS settings display. - Strengthened drag-and-drop folder uploads in cozy-drive with batch processing for large directories, preventing stale FileSystemEntry references and improving reliability for bulk uploads. Major bugs fixed: - cozy-stack: corrected deletion messaging by using the instance settings email for force deletion, aligning with the registration service resolution flow; added tests for edge cases and failure modes. - cozy-drive: fixed drag-and-drop for large folders by batching readEntries to avoid NotFoundError and ensuring completed uploads reflect promptly; updated formatting and batch handling for readability and stability. Technologies/skills demonstrated: - RabbitMQ-based event-driven architecture, message publishing, and routing - Go language patterns, interface design, and unit testing - Microservice lifecycle management and graceful shutdown - Batch processing and client-side update strategies for large datasets - Observability considerations via stable shutdowns and error handling Overall impact: Improved security, reliability, and user experience across core SaaS workflows. Delivered scalable patterns for event-driven user lifecycle management and robust file-handling capabilities to support growing data volumes.
