Can you build both the API and the UI?

Yes. That's the point of full-stack. My SaaS project is a full end-to-end build: multi-tenant data model in Prisma/PostgreSQL, the API, and the React front-end.

Do you do authentication and integrations?

Yes, including REST API integrations and third-party services, which I do regularly in WordPress work too.
