Familiarity with both immediate mode and retained mode GUI implementations. Experience building in-viewport interaction such as gizmos, manipulators and brushes, alongside panels and property editors. Shipped artist-facing tools where feel was part of the acceptance criteria. Fluency with modern AI tooling across development and the work around it, using it to move faster while retaining the judgement to catch its failures and stand behind the quality of what ships.
