I've been using AI tools to help with frontend development, but it's been pretty ad hoc so far, mostly generating components on demand without much structure.

I’d like to move toward a more traditional and sustainable workflow: - Start with UI/UX design - Create a design system from those designs - Implement components that are reusable across the app

Before even prompting an LLM to write code, I want to establish a solid foundation that makes the AI's output more consistent and maintainable.

What workflows, tools, or practices do you use to go from design to implementation in a way that scales?

Bonus points for open source solutions, but I’m open to any ideas, tools, scripts, design systems, or even just habits you've adopted that help keep things coherent.
