I created an online multiplayer typing game using Next.js, Node.js, and Socket.IO. Players can compete with each other in real time over the internet.

An app designed to help users stay focused while reading by highlighting text one line at a time. It uses OCR to extract text from the camera and highlights sections separated by designated markers.

A tool for easily running live streams in Scratch. It uses Scratch cloud variables to support simple live streaming, preset chat messages, movable on-screen sprites, and preconfigured slides.

A game where you move a player through a 3D space and try to reach the goal. I created it as practice for JavaScript.

A homepage I created during the summer of my first year of junior high school as practice for text-based programming.

A 3D graphics program that allows movement and rotation at the same time using the arrow keys.
