Dec 1, 2025December 2025 monthly summary: Delivered critical data integrity improvements and user-facing UI enhancements, while refining configuration for SharePage to honor user theming and localization preferences. Key outcomes include: (1) cascading deletes for revenue and segment tables to preserve data consistency when websites are removed; (2) UI stability improvements via PageHeader type-safety fixes; (3) date range filter reliability with numeric offset handling; (4) legend readability improvements by truncating long labels in the metrics component; (5) SharePage enhancement to expose theme and locale via URL parameters, with subsequent refinement to remove locale code. An exploratory board feature lifecycle change was rolled back to maintain system stability.

Nov 1, 2025In 2025-11, delivered a UI consistency enhancement in the umami app by centralizing the maxHeight style property into the DialogButton component, removing per-button maxHeight usage and ensuring uniform button height across all dialogs. This improves layout consistency, responsiveness, and maintainability by reducing duplication and simplifying styling at the component level. Commit a6d4519a980dc301c7675ccf7ab69137b5469351 ('set maxHeight for DialogButton. remove from individual buttons'). No major bugs fixed this month; focus was on UI polish and code maintainability. Technologies/skills demonstrated: React component design, UI refactoring, and clear, traceable commit hygiene.
