Worked on the vatesfr/xen-orchestra repository, delivering robust backend features and reliability improvements across backup, API, and virtualization workflows. Developed REST API endpoints for resource and backup management, implemented AES-256-GCM encryption for Redis credentials, and enhanced backup merge logic to support resume after interruptions. Addressed race conditions, disk initialization errors, and improved observability with detailed logging and monitoring. Leveraged JavaScript and TypeScript in a Node.js environment, applying security best practices, dependency injection, and test-driven development. The work enabled automation-friendly operations, strengthened data integrity, and reduced operational risk for large-scale virtual machine management and backup systems in production environments.

May 1, 2026May 2026: Delivered security, API, and reliability enhancements for xen-orchestra. Key features include Redis credential encryption (AES-256-GCM) with data migration, secure key management, and HMAC-backed indexing maintaining backward compatibility; REST API improvements with dynamic route registration and a new VM revert-to-snapshot route; and improved VM boot order handling for HVM VMs to ensure correct install methods and prevent unintended network boots. Also stabilized backup merge operations to address OUT_OF_RANGE errors. Overall impact: stronger data security, more flexible VM lifecycle management, and robust backup/restore reliability, reducing risk and operational overhead. Technologies demonstrated include AES-256-GCM encryption, secure key management, HMAC indexing, dynamic REST API routing, VM install-method driven boot logic, and test-driven robustness.

Feb 1, 2026February 2026 focused on delivering automation-friendly features, strengthening storage and resource management capabilities, and stabilizing critical backup and merge workflows across the Xen Orchestra stack. Key REST API work enables programmatic control of VIFs, PBDs, and storage operations, with space reclamation and SR scanning exposed for automated lifecycle management. The backup stack was rewritten to boost performance (notably for block-mode backups) and to robustly handle remote VHD disk chains, improving reliability for large-scale deployments. Race conditions in merge processes were addressed to prevent intermittent failures during remote-disk and backup merges. The MCP AI Assistant Server was released, along with web-core and backups API updates, enabling AI-assisted operations and broader automation. Ecosystem package updates across core components (fs, web-core, backups, etc.) were orchestrated with a consolidated release, including pertinent version bumps. Finally, a CPU provisioning calculation fix and corresponding version updates were completed, with changelog updates and new release badges for 6.2.1.
