- Use TypeScript, React, Next.js, Redux Toolkit, React Query, and browser storage tools (localStorage, sessionStorage, cookies) to build seamless, fast experiences.
What We’re Looking For
- 3–5 years of professional experience in web development.
- Experience building or maintaining SDKs, libraries, or frameworks that ship to external developers.
- Strong understanding of fundamentals, internals, and system design.
