How to Fix React Native Lag, Memory Leaks & Hit 60 FPS in Production

Why production React Native apps drop frames on mid-range Android devices—and the exact JSI, FlashList, Reanimated, and memory-profiling fixes used to restore locked 60 FPS fluidity.

Eliminate JS-thread frame drops by migrating heavy scroll views to recycled FlashList layouts and memoized item cells.

Frequently Asked Client Questions

Everything you need to know about initiating direct mobile engineering contracts.

How do you handle Apple App Store & Google Play Store approval?

I take full ownership of the store submission process: provisioning profiles, bundle metadata, Apple Human Interface Guidelines (HIG), and Google Play policy compliance. If reviewers request changes or raise guideline questions, I actively revise code and resolve reviewer feedback directly to get your application approved and live in production.

What services are included in ongoing mobile app maintenance retainers?

Maintenance retainers cover regular iOS/Android updates, Expo SDK upgrades, third-party library maintenance, proactive bug resolution, crash monitoring (Bugsnag/Sentry), and fast-response priority SLAs for production hotfixes.

Can you conduct a code audit of an existing React Native app?

Yes. I conduct full architecture, security, and performance audits for existing apps to identify bridge bottlenecks, memory leaks, unoptimized re-renders, and deliver an actionable 60 FPS remediation roadmap.

Do you build full-stack web applications alongside mobile apps?

Yes. In addition to mobile apps, I engineer full-stack web applications, admin portals, and client dashboards using React, Next.js, Node.js, and Supabase with unified API backends.

How do direct contracts & retainer payments work?

We initiate milestone-based contracts or monthly retainers via Stripe Invoicing, Deel, or Wise Business. This eliminates high marketplace cuts while offering standard legal protections, clear deliverables, and zero-hassle invoicing.

Who owns the code and intellectual property (IP)?

You retain full, exclusive ownership of all source code, design assets, and repository IP from day one. I deliver clean GitHub repositories with complete architecture documentation.

How do you align with US, EU, or international time zones?

I maintain flexible overlap windows (typically 4-6 hours daily) for US, European, and Asian client syncs, async daily video updates, and regular milestone demos.
