  upload flows

  (drag-drop, chunked/parallel, retry/resume), progress UI, and error states.
• Add

  offline-first capabilities

  : Service Workers, IndexedDB, background sync/merge logic, and conflict resolution UI.
• State & data:

  or Redux for caching, optimistic updates, and invalidation.
• Forms & validation:

  React Hook Form + Zod

  (or Yup) with a11y-friendly controls.
• Performance & UX: code-splitting, lazy routes, web workers for heavy tasks, skeletons, toasts, and accessibility.
• Auth & routing: JWT/OAuth flows, role-aware navigation, protected routes (React Router or Next.js).
• Testing & quality:

  Jest + React Testing Library

  , basic

  Cypress

  E2E on critical flows; type-safe APIs with shared types.

Back-end & Infra

• Work with our back-end team to design/consume REST/GraphQL endpoints.

• Basic PHP (Laravel) knowledge

  to read controllers/routes, understand request/response shapes, and make small fixes or add simple endpoints when needed.
• Comfort with any of:

  Node.js/Express or NestJS

  or

  Python/FastAPI for upload handlers and webhooks.
• Storage & delivery:

  AWS S3

  and

  resumable upload

  patterns; understanding of performance trade-offs.
• Solid understanding of

  auth/authorization

  (JWT, roles) and secure API consumption.

• Basic PHP (Laravel) literacy

  — enough to read/adjust routes/controllers, debug integration issues, and collaborate with PHP services.
• Clear communication in English and comfort owning a feature end-to-end.

Nice-to-have

• Node/NestJS

  or

  Python/FastAPI service experience; Docker/Kubernetes familiarity.
