React MERN Bug Fixes

My production React front-end is showing its rough edges: form submissions intermittently fail, data sometimes renders inaccurately, and certain user interactions feel sluggish. These are clear functional errors with an extra dose of performance trouble, all confined to the React layer of a typical MERN build.

I need a developer who can dive straight into the existing codebase, trace the root causes, and patch them without disturbing stable modules. Expect to work with modern React (hooks, context, maybe a sprinkle of Redux) alongside the usual REST calls coming from our Node/Express API.

Deliverables
• Reliable form submissions—no console errors, network retries, or unexpected reloads
• Accurate, real-time data display that survives page refreshes and route changes
• Snappy user interactions; key components should render under 100 ms and avoid blocking the main thread
• A concise changelog or pull request notes so I can follow what was tweaked

Acceptance
I’ll test each affected screen: forms must persist data, lists must mirror the database, and UI performance should feel immediate on a mid-tier laptop. Pass those checks and we’re done.
