Expert performance for JavaScript applications. We find and fix JavaScript-specific performance issues that affect production apps. From $19.
JavaScript performance issues we find
Common performance problems specific to JavaScript applications.
Memory leaks from closures and listeners
Event listeners, intervals, and closures that capture large objects are never cleaned up, causing memory consumption to grow over time.
What our JavaScript performance covers
Page load speed
Bundle size optimization, code splitting, image optimization, and reducing time to first meaningful paint.
Runtime performance
Eliminating unnecessary re-renders, optimizing state management, and fixing memory leaks.
Database optimization
