Developer Builds Scheme-to-WASM Compiler in 4 Days Using AI Assistance
By
MatthewPhillips
A respectable bake. You'd come back tomorrow for another.
Summary
A developer shares their experience building a Scheme compiler called Puppy Scheme that compiles to WebAssembly (WASM) using AI assistance. The project was completed in just 4 days, with most work done over a weekend plus some weekday evenings. The developer used Claude AI to optimize performance, which dramatically reduced compilation time from 3.5 minutes to 11 seconds overnight. The project was inspired by seeing others quickly build near-production level projects that would normally take months or years.

I call it Puppy Scheme.
This is a side project so I'm not exactly sure the total number of hours I spent; it was most of last weekend plus an hour or two a couple of weekday nights, but that's really it.
One night before I went to bed I told Claude to 'grind on performance' and when I woke up it had taken compilation time from 3½ minutes down to 11 s
