| Aspect | React Query |

|---|---|
| Work Environment | Frontend development, UI/UX focus, JavaScript/React projects |
| Industry Usage | Web applications, SaaS platforms, e-commerce sites |
React Query is a library for managing server state in React applications, focusing on data fetching and caching. A React Developer builds entire user interfaces, often using React Query as a tool within their skill set. While React Developers need broader knowledge of React, JavaScript, and UI design, React Query specialists focus on efficient data management within React apps. Both roles often overlap in web development teams, but React Query is a specific library skill, whereas React Developer is a broader role.

At Newcode.ai, we're on a mission to reshape how organizations put AI to work in their day-to-day operations. In few months, we've moved from vision to reality-building products our clients truly love. As part of our fast-growing and highly ambitious team, you won't just drive the future of AI-you'll help define it.
The roleYou'll build features the whole way through: the FastAPI service and data work on the back, the React interface on the front. Most of what we build puts a language model in front of someone doing real work, so a typical feature might mean wiring up retrieval and an LLM call on the backend, then building the streaming, document-heavy UI that makes it usable.
We want someone who can carry a feature from idea to production without handing it over a wall. You should be at home in a Celery task and in a React component, and able to handle routine work on either side without waiting for a specialist to unblock you.
Requirements
What You'll DoNice to have: Next.js, React Query, Zustand, shadcn/ui; LangChain or LlamaIndex; streaming over SSE or WebSocket.
