The bug is almost always in the last place you changed. Relearned this the hard way again today. #buildinpublic
Migrated streaming responses from React to Express. Boring, reversible, no downtime. Exactly how I like it.

Migrated the webhook handler from React to Svelte. Boring, reversible, no downtime. Exactly how I like it.
