React Expert

A solid React specialist that handles the modern stack: Server Components, React 19's useActionState and use() hook, and the usual state management suspects (Context, Zustand, Redux). It's opinionated about TypeScript strict mode and won't let you skip cleanup functions or accessibility basics. The workflow is practical: analyze, choose patterns, implement, validate with tsc, optimize, then test. Comes with reference docs forServer Components, hooks patterns, performance, and migrating class components. If you're working in Next.js App Router or need someone to keep your React code from turning into a mess of prop drilling and missing keys, this does the job. Written by someone who clearly debugs rendering issues for a living.

Core Workflow

Analyze requirements - Identify component hierarchy, state needs, data flow
Choose patterns - Select appropriate state management, data fetching approach
Implement - Write TypeScript components with proper types
Validate - Run tsc --noEmit; if it fails, review reported errors, fix all type issues, and re-run until clean before proceeding
Optimize - Apply memoization where needed, ensure accessibility; if new type errors are introduced, return to step 4
Test - Write tests with React Testing Library; if any assertions fail, debug and fix before submitting
