Worked on the wowsims/sod repository to deliver a feature that enhances batch item customization by integrating rune support into the bulk item picker. Developed a UI flow in React and TypeScript that checks rune eligibility for each item slot and opens a selector modal when applicable, enabling users to apply runes across multiple items simultaneously. Updated the bulk_item_picker.tsx component to handle these eligibility checks and batch operations, streamlining the process and reducing manual steps. Focused on front end development using JavaScript and TypeScript, the work improved workflow efficiency for users managing large sets of items with rune-driven enhancements.
