March 2025 monthly summary for IgniteUI/igniteui-angular focusing on test infrastructure improvements around the Query Builder drag-and-drop (DnD) functionality. Delivered modular test refactors and enhanced test coverage to raise reliability and maintainability, enabling faster iteration and CI confidence.

February 2025 highlights robust, value-focused delivery of Query Builder capabilities across samples and docs. In IgniteUI/igniteui-angular-samples, we shipped: (1) Query Builder Template Sample Enhancements with routing, migration to an entities-based data model, and refined filtering and UI (ShipVia/ShipCountry, scrollability, layout spacing); (2) Query Builder Style Sample Enhancements delivering multi-entity support, lint fixes, dark theming, and theming consistency; plus Dependency and Build Maintenance to revert unintended package.json/package-lock changes and restore stable dependencies. In IgniteUI/igniteui-docfx, we expanded Query Builder docs with drag-and-drop and keyboard interaction guidance, updated visuals (GIFs), and improved examples. Overall impact: improved developer experience, faster onboarding, more realistic demos, and more stable builds. Technologies/skills demonstrated: Angular/TypeScript, routing, data modeling (entities-based data model), UI theming and CSS, linting, build maintenance, documentation authoring with GIFs and examples, and DocFx tooling.
