A self-contained utility that parses robots.txt content into a structured object (allow/disallow rules, sitemaps, crawl delay, host). It handles edge cases (wildcards, comments, HTTP/HTTPS protocols) and is fully testable. Could be extracted into a standalone npm package or reused in any project needing robots.txt parsing. Demonstrates careful edge-case handling and clear separation of concerns.

A fully featured Vue 3 pagination component with first/prev/next/last buttons, ellipsis, page number buttons, and slot-based customization. It handles edge cases like single page, boundary conditions, and keyboard navigation. The component is self-contained, uses only reactive props and emits, and can be easily extracted to any Vue 3 project. Demonstrates non-obvious skill in handling pagination logic and accessibility.

A generic popover component with a trigger button, smooth transition animations, and a slot for arbitrary content. It manages open/close state, handles click outside to close, and supports keyboard navigation. The component is isolated with no internal dependencies beyond Vue 3, making it reusable across any Vue 3 application. Demonstrates clean encapsulation of interactive UI patterns.

An SVG-based circular gauge component for displaying scores (e.g., Lighthouse scores). It supports both a full gauge and a stripped mode, animates smoothly, and color-codes scores based on thresholds. The component is self-contained, uses only props and computed properties, and can be reused in any Vue 3 project needing a gauge visualization. Demonstrates clean SVG manipulation and animation logic.
