Frontend Platform Labs
Production-grade frontend platform work — component APIs, design tokens, codemods, prod triage, and migration strategy.
How labs work
- Follow the steps in the task panel.
- Edit the highlighted file — usually
the highlighted file. - Watch the preview update as you type.
- Run tests when you think you are done.
- Open hints if you get stuck — they reveal one at a time.
After this path
- Design stable compound component APIs
- Normalize design token schemas across themes
- Write safe AST codemods for migrations
- Triage production errors from observability evidence
- Ship a strangler migration slice behind feature flags
