React bug fixing & Next.js debugging help

When a frontend bug is blocking progress, I can help trace the actual cause instead of rewriting unrelated parts of the project.

Problems I can investigate

Hydration errors

Track down server/client markup differences, browser-only values, invalid nesting, and other causes of Next.js hydration mismatches.

React state not updating

Inspect stale closures, direct mutation, batched updates, and component identity issues that make state or the interface look frozen.

Render and effect loops

Find unstable dependencies or update cycles behind repeated renders and infinite useEffect loops.

Production-only failures

Compare environment variables, build behavior, routing, caching, and browser output when a Next.js app works locally but fails after deployment.

Before requesting help

A useful starting message includes the exact error, what you expected, what actually happened, the relevant component or route, and the smallest set of steps that reproduces the problem. If the issue only happens in one environment, include that too.
