This is urgent task! Please apply if you can finish this within near time soon! My production-level Next.js site has been showing functional errors ever since I added a new feature set. Pages that once rendered instantly now spike memory and CPU usage until the service restarts, and a few user flows break mid-request. The codebase is on the latest stable Next.js with React, Node, and a Vercel deployment pipeline, but I’m open to alternative debugging tools if they speed things up. What I need you to do is pinpoint the root cause of the memory/CPU surge, correct the underlying bug, and return the app to its previous stability without stripping out the new features. SSR, API routes, and any custom server logic are all fair game for investigation. Deliverables • Diagnosis report that explains the specific cause of the functional errors and resource spikes • Patch or refactor that resolves the issue and passes unit/integration tests • Validation on a staging branch, followed by a clean deployment to production once confirmed stable Acceptance criteria The service must run for 24 hours in production without abnormal memory growth, CPU spikes, or broken routes, and all automated tests must remain green. If this sounds clear and you have deep Next.js profiling experience, let’s get the bug exterminated.
