Jonas Koberg contributed to the opencloud-eu/opencloud and owncloud/reva repositories, focusing on backend development, API integration, and access control using Go and WebDAV. Over five months, he delivered features such as parallel metadata retrieval, OCM-based file locking, and flexible domain authorization, while also addressing bugs in quota calculation, storage deletion, and permission enforcement. His work emphasized reliability and maintainability, including dependency upgrades, changelog automation, and documentation improvements. By refactoring resource ID handling and optimizing concurrency, Jonas enhanced system robustness and performance, ensuring secure, multi-tenant readiness and streamlined release processes across distributed cloud storage and collaboration platforms.

February 2025 — Owncloud/reva: Delivered a critical OCM Wildcards Handling and Permissions Bug Fix, strengthening federated provider authorization and permission enforcement. Implemented safeguards to prevent cached wildcard provider data from being overwritten, refactored service endpoints to substitute wildcard domains with normalized ones, and addressed related view/download permission issues surfaced in release notes. This work culminated in the v2.27.4 release (commits: de27ef90f9abbf5f873f808a7fc30ef1c3be217b; 178017607c04a93d014ac2a7eafc67a2efc570e6).
