React Native Performance Optimization

I help teams find and fix React Native performance problems that make an app slow, unstable, or frustrating to use. The work starts with a specific journey and a measurable baseline, then focuses on the code and data flow behind the problem.

WHO IT’S FOR

When this service makes sense.

This service is for teams with an existing React Native app that opens slowly, re-renders too often, crashes, or keeps users waiting for data. You can come with measurements or simply show me where the product feels wrong.

WHAT’S INCLUDED

Work we can include.

Startup and data loading

I review what happens while the app opens, including API calls, local data, and work that blocks the first useful screen. On Khedmah Delivery, caching and API changes reduced typical opening time from 4–8 seconds to 2–3 seconds.

Rendering and interaction

I trace unnecessary re-renders, large-list bottlenecks, repeated calculations, and interactions that feel delayed. On Khedmah Delivery, this work also included animation and Figma-led refinements informed by event tracking.

Crash investigation

Firebase or Sentry reports help connect production failures to reproducible problems and release priorities. Khedmah Delivery’s crash-free session rate improved from 90% to 100% during a measured three-month period in Firebase.

Offline data and background sync

Local data and background synchronization can keep users moving while fresh information downloads. On SnapHatch, this approach allowed continued use during downloads and produced a measured 20% faster startup.

HOW IT WORKS

From first conversation to delivery.

  1. Identify the affected screens, devices, and user actions.
  2. Review existing performance evidence, crash reports, and relevant code.
  3. Prioritize and implement fixes, then compare behavior with the baseline.
  4. Document the changes and agree on any follow-up monitoring.

QUESTIONS

Useful details before we begin.

How do you measure improvements?

We establish a baseline for the affected journey, implement focused changes, and compare performance and stability against that baseline.

Do you also improve the interface?

Yes. UI/UX refinements and animation work can be included when they support the performance and usability goals.

Can this start as a focused engagement?

Yes. We can agree on a specific startup, screen, or stability problem rather than a full application rebuild.

NEXT STEP

Share the project context.

Share the affected screens, devices, reproduction steps, and any timing or crash reports you have. You don’t need to diagnose the cause first; code access and measurement details can be arranged privately.
