Hi! I can help you diagnose and fix the performance issue on your Node.js backend. I'd start by profiling the server, checking for blocking operations, slow database queries, and memory leaks. Usually it's one of those three causing the slowdown. I've solved similar issues before where a single unoptimized Mongo query or a missing index was tanking response times. I can start right away and typically diagnose these within a couple hours. I'll document everything I find and change so you have a clear picture after. I'm Edward, 10+ years building and debugging web apps. Let me know if you want to discuss and I'll get started as soon as I have repo access.

I can jump in quickly to diagnose and fix the Node.js backend performance regression without disrupting the existing React frontend. I’ve handled similar issues involving slow database queries, event loop blocking, memory leaks, inefficient middleware chains, unoptimized background tasks, and connection pooling problems in production Node.js applications. My approach is to profile the backend, isolate the bottleneck from logs/runtime behavior, implement a clean fix, and verify performance improvement without regressions. Estimated turnaround for diagnosis and fix is typically a few hours depending on codebase complexity, and I’m available to start immediately once repository access and logs are shared.

Hi there ? Could you share whether the slowdown appears during specific API routes or across all requests? Also, do you currently have any monitoring or logs (PM2, APM, or server logs) that show CPU, memory, or query timing during the slowdown? The project is straightforward, but it may still take a bit of time to complete properly. I’ll start by profiling the Node.js server to identify blocking operations, inefficient database queries, memory leaks, or middleware bottlenecks. Once the root cause is confirmed, I’ll implement a clean fix and review related areas to ensure the issue doesn’t reappear. All changes will be documented clearly, tested for stability, and validated to confirm response times are restored without regressions. You’ll also receive a short report of the diagnosis, files changed, and optimization suggestions, along with 6 months of post-delivery support. Feel free to share the repository access and logs, and I can start right away ? Best regards ?

Hi, Your Node.js backend performance drop is likely causing slow API responses and poor React UX, and you need the exact bottleneck identified and fixed without affecting stability. I will quickly isolate whether the issue comes from blocking code, database queries, or middleware inefficiencies affecting response time. I’ll use profiling tools like Node Clinic, PM2 metrics to pinpoint event-loop blocking, memory leaks, or slow DB queries. Then I’ll optimize middleware flow, refactor heavy functions, and tune database indexes or caching where needed for stable performance improvement. I have strong experience debugging production Node.js APIs and React-integrated systems under load. I also ensure fixes are regression-safe with measurable performance gains. Bonus: I can add lightweight monitoring and caching recommendations for future stability. Shall I start by reviewing your logs and API endpoints to pinpoint the slowdown? https://www.freelancer.com.bd/u/mhmamun360 Best regards, Md Mamun Hossain
