Our Express API on a 4 GB server climbs from 200 MB to over 1 GB and gets killed by the OOM killer roughly every 6 hours. We restart it with PM2 as a workaround. I need heap snapshots or profiling used to find the leak (we suspect an in-memory cache and unclosed streams), a fix, and a load test showing memory stays flat.

Short outages at random times, usually during peak traffic.

Key Deliverables:

• Codebase Review & Initial Implementation: Reviewing existing code, setting up development environment, and beginning core work.

• Feature Implementation & Testing: Completing primary deliverables with automated and manual testing.

• QA Verification & Production Deployment: Final cross-browser/device testing, staging verification, and production handoff.

Requirements:

• Demonstrated experience with Node.js, Express, Memory Profiling, Debugging, Load Testing

• Quick turnaround needed — must be available to start within 24 hours.

• Must test on both mobile and desktop before requesting milestone release.

• We can only provide staging access initially, not production.

If you have experience with this type of project, we'd love to hear from you. Please include relevant work samples with your bid.
