Case studies
End-to-end scenarios with the same CCDAO lens you would use in design reviews: collect constraints, structure the UI, model data, shape APIs, and optimize for scale, reliability, and accessibility.

This site is for practicing frontend engineers who want to level up on real product-shaped problems: boards, feeds, chat, search, media-heavy pages, and collaboration surfaces.
Case studies walk through requirements, structure, data, APIs, and trade-offs the way you would on a growing team. Patterns spell out what often breaks in production and how to harden it.
Patterns
Reusable building blocks with decision criteria, failure modes, and testing ideas so you can adopt or adapt them in your own codebase.
