January 2026 monthly summary focusing on delivering safer tooling, UX consistency, and maintainability enhancements across three repositories. Key features delivered include a configurable Babel plugin propertyValidationMode for disallowed shorthand properties, enabling throw/warn/silent modes and renaming the option for clarity; and a new lint rule noExcessiveLinesPerFile for CSS and GraphQL to improve readability and maintainability. Major bug fixed in actualbudget/actual: the month filter date display now respects the user's configured date format setting instead of always defaulting to mm/yyyy, improving UX consistency. Overall impact: safer code transformations, more predictable user experiences, and stronger code quality standards that reduce noise and maintenance effort. Technologies/skills demonstrated: Babel plugin configuration, date formatting logic, and lint rule authoring with clear commit traceability.

December 2025: Mobile overspending flow stabilised in actualbudget/actual. Fixed stale amounts in the cover overspending modal and ensured the UI returns to the budget view with updated data after the action, improving mobile reliability and user trust.
