· Expert knowledge of React, TypeScript, and browser fundamentals

Additional Qualifications

· Deep experience with:

o Styling systems and UI architecture

o State management patterns

o Real-time frontend systems

· Proven track record of leading frontend architecture at scale

Core Responsibilities

Frontend Architecture / System Design
