Notes Nest
A note-taking app built as a complete commercial slice rather than a demo: real authentication, real subscription billing, and a typed Postgres backend behind the editor.

Most side-project note apps stop at the editor. This one was built to prove out the parts that actually make a product sellable.
- Authentication via Kinde and subscription billing via Stripe.
- Next.js and TypeScript on the front, Prisma and PostgreSQL behind it.
