The listing is aimed at the following profile: 1+ years. For general context: React is a popular library for building interactive user interfaces. Node.js lets developers run JavaScript on the server. Interested candidates can review the full details below and apply using the link provided on this page.

★ TypeScript: Adds types to JavaScript so mistakes are caught earlier; day to day it means defining interfaces and typing function inputs and outputs.
★ React.js: Building user interfaces from reusable components and managing the data that changes on screen.
★ Node.js: Running JavaScript on the server to build APIs, handle requests and talk to databases.
★ REST APIs: Designing and consuming HTTP endpoints so a front end, mobile app or another service can exchange data.
★ HTML and CSS: Structuring web pages and styling them so they work well on different screen sizes.
★ Docker: Packaging an application and its dependencies into containers so it runs the same way everywhere.
★ AWS: Using cloud platform services for hosting, storage and databases instead of managing physical servers.
★ Artificial Intelligence: A general understanding of how AI systems learn from data, where they are useful, and where they can be unreliable.

★ TypeScript: interfaces versus type aliases, generics basics, typing API responses
★ React.js: components, props and state, useState and useEffect, lists, forms and conditional rendering
★ Node.js: npm and modules, building a simple REST API, asynchronous file and network operations
★ REST APIs: HTTP methods and status codes, authentication basics such as tokens, validation and error responses
★ HTML and CSS: semantic HTML, Flexbox and Grid, responsive design
★ Docker: Dockerfile basics, images versus containers, docker compose
★ AWS: core compute and storage services, permissions and access control, basic deployment
★ Artificial Intelligence: supervised versus unsupervised learning, common real-world use cases, limitations and bias

This role may be suitable for candidates who bring substantial experience and are comfortable owning technical decisions and supporting other team members. Applicants with working knowledge of TypeScript, React.js, Node.js, REST APIs, HTML and CSS and Artificial Intelligence may feel well prepared for what the listing describes. A remote arrangement may suit people who work well independently and communicate clearly in writing. This is editorial guidance only, and the employer makes the final decision on suitability.

Applicants may want to highlight relevant experience with TypeScript, React.js, Node.js and REST APIs in their CV. If you have used AI tools or built small projects with language models, briefly describe what you built and how you checked the results. Keep your CV to the point and tailor the summary to this role rather than sending a generic version. These are general tips, not requirements stated by the employer.
