Next.js Developer Needed for App Router State & Caching Bug Fixes

I am looking for a Next.js developer to troubleshoot and resolve a few specific state synchronization and caching issues in an existing web application. The core application is fully built and mostly functional, but certain dynamic routes are experiencing hydration mismatches, client-side state desynchronization after server mutations, and unnecessary re-render loops during navigation. The developer will review the current component architecture, audit our Server Actions and caching logic, and refactor the problematic dynamic flows. The goal is to ensure seamless client-server state revalidation, eliminate hydration errors, and optimize frontend performance while keeping existing features stable. The ideal candidate should have strong diagnostic skills and be comfortable debugging complex state edge-cases in pre-existing production codebases rather than building strictly from scratch. Required Skills: - React.js / Next.js (App Router expertise) - TypeScript - Server Actions - State Management & Custom Hooks
