2025-09 Monthly Summary — Key features delivered across two repositories improved UX and documentation quality: In umbraco/UmbracoDocs, ContentSortedNotification was added to the ContentService notifications, and the README was updated to improve discoverability of the new notification type. In umbraco/Umbraco-CMS, Document Picker drag-and-drop UX was refined with new CSS rules to visually indicate drop targets, with legacy opacity-based drag placeholder styling removed from the relevant components. Major bugs fixed include correcting the MediaSavingNotification documentation link to point to the correct Umbraco v13 API docs. Overall impact: enhanced developer experience, faster onboarding, and clearer editor workflows, contributing to more reliable content publishing and API usage. Technologies/skills demonstrated: frontend CSS/TS styling, documentation governance, and Git-based collaboration with a focus on UX and maintainability.

July 2025 (2025-07) – Focused on improving data correctness in the Umbraco CMS user data retrieval flow. Delivered a critical pagination fix that ensures accurate total counts for user data and prevents broken pagination in admin UIs. The change tightens data access patterns by applying ordering before counting and computing the total item count prior to skip/take, delivering a more reliable and scalable user listing experience. This work reduces UI inconsistencies, support tickets related to pagination, and improves trust in API responses. The change was implemented in the umbraco/Umbraco-CMS repository with the following commit reference: 73c995c8ec589d2e63bf09169c2bca5cac9e6bc2 (commit message: "#19775 fixed get user data by applying OrderBy after counting (#19776)").
