Projects
Roux Solver
Roux Solver is an interactive web app that teaches users how to solve a scrambled cube using the Roux method. Built with Three.js, it renders a smooth, animated 3D cube directly in the browser. Users can enter their own scramble or generate a random one, then follow step-by-step Roux method instructions tailored to the scramble. The app includes multiple speed settings for animations and solution playback.
Palladium
Palladium is a hobby programming language developed in Rust featuring a clean, Python-inspired syntax with a focus on readability and developer ergonomics. The language compiles and transpiles into Java, allowing programs to run on the JVM while abstracting away much of Java’s verbosity. This project involved building a lexer, parser, and abstract syntax tree (AST), along with code generation targeting Java, and provided hands-on experience in language design, compiler construction, and JVM-oriented tooling.
