In my second year of junior high school, I began exploring Chrome extensions. Tools that could change a page’s behaviour, such as dimming the screen around a YouTube video, made me want to understand how they worked. I learned to develop and publish extensions, then made several of my own.

Easy QR Code generated a QR code for the current page or for custom text and links.

Page Muter muted audio or video in the current tab.

Image Fetcher downloaded a page's images in a batch.

SA Fetcher brought a simplified version of the Scientific American downloader into the browser.

WeChat Spamming automated repeated messages in WeChat as a prank tool.

These screenshots show the developer dashboard and several of the extensions.
