Teams whose Node.js/Next.js SSR servers crash every few hours with `FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory`—or whose React SPA tabs balloon to 2GB+ of browser RAM—urgently search to hire a freelance JavaScript/Node.js memory leak & heap snapshot debugger programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer.
Core Heap Snapshot & Memory Leak Remediation Capabilities
- Chrome DevTools Heap Snapshot & Allocation Timeline Diffing: Capturing and comparing `.heapsnapshot` profiles (`MemLab` / Chrome DevTools / `v8.writeHeapSnapshot()`) to pinpoint detached DOM trees, uncleaned `EventEmitter` listeners, unbounded module-scope `Map`/`LRU` caches, and closures retaining large buffers.
- Next.js SSR & Node.js Server Leak Fixes: Eliminating singleton request-context leaks, unclosed database/Redis/WebSocket handles, and global state pollution across SSR renders.
- React Re-Render & Flamegraph Profiling: Fixing cascading context re-renders, unstable hook dependencies, and virtualization bottlenecks.
Frequently Asked Questions
How do you find a memory leak that only happens after 6 hours of production traffic?
I configure non-intrusive heap-usage telemetry and automated heap-dump triggers (or run accelerated `MemLab` / Playwright multi-step navigation loops in staging) to compare retained object dominator trees before and after garbage collection.
How do I hire you to fix a Node.js or React memory leak?
Hire me via Upwork.
