Lab

Side projects you can open right here.

Games and tools I build when nobody is paying me to. Each one runs in the browser — no install, no account, no launcher.

Games

Built in Unity and played right in the page.

Speed

A small arcade racer built in Unity. Runs in the browser, nothing to install.

Tools

Developer tools that run entirely in your browser.

Z80 Emulator

A Zilog Z80 you can program in assembly or C: registers, memory, breakpoints, and a pixel display.

simplos

A hobby operating system, written from scratch in Rust. Boots in your browser on an emulated PC.

Write-ups

How the things here are built, in long form.

This Website

lazyscript.com from the inside: Rust from the database to the browser, islands of WebAssembly, and Google Cloud run entirely from Terraform.
