Essential:
- 5+ years of professional TypeScript / JavaScript development.
- Expert-level React with modern patterns across SPA applications.
- Strong experience with modern build tools (Vite, Turbo, webpack) and monorepo management.
- A pragmatic approach - you understand the trade-offs between abstraction and clarity.
Nice to Have:

- AWS CDK, Tailwind CSS, Shadcn/Radix components.
- Zod validation and Playwright E2E testing.
- React Native exposure.
