Every time I started a new Next.js project, I lost the first week to setup.

Authentication. Internationalization. Role-based access. SEO meta tags. Environment validation. Error monitoring. Linting. Testing. CI pipelines.

By the time I had a working foundation, the excitement was gone, buried under config files and boilerplate glue code.

After doing this across multiple SaaS projects, I stopped and asked myself: What if I built the foundation once, properly, and never had to do it again?

So I did. Then I rebuilt it from scratch with a feature-sliced architecture and a clearer frontend-first scope.
