After years of building and rebuilding, this is the architecture I've landed on as a solo developer.
Everything is TypeScript. Everything is type-safe end to end.
I wrote down the whole setup ↓
I built a Claude Code Skill / Codex Skill that turns a SaaS idea into a full-stack app.
One prompt. One turn. Zero manual edits.
It generates auth, multi-tenancy, RBAC, i18n, dashboards, database, tests.
Try it:
npx skills add ixartz/saas-boilerplate
/saas-builder <your idea>
