About this Gig
Is your React Native app slowing down, crashing, or behaving unpredictably? I can step in and get it back under control.
I specialize in diagnosing issues that hide deep inside production codebases. My focus isn't just fixing visible bugs, but understanding why they happen. I review your architecture, state management, and API interactions to uncover bottlenecks and structural problems that often go unnoticed.
What I can do for your app:
- Crash Resolution: Fixing fatal errors on iOS and Android.
- Performance Optimization: Resolving memory leaks, slow renders, and UI freezes.
- Code Audits: In-depth review with a clear roadmap for tech-debt removal.
- Dependency Updates: Safely upgrading React Native, Expo, and outdated libraries.
- UI/UX Fixes: Correcting responsive design issues across different screen sizes.
The result? Cleaner code, rock-solid stability, and an app that performs exactly the way your business needs it to.
Please message me before ordering so we can discuss the specific issues you're facing and review your codebase.

FAQ
Can you fix an app originally built by another developer?
Yes, absolutely. Most of my maintenance work involves taking over existing codebases, analyzing the previous developer's structure, and bringing it up to industry standards.
What do you need to start investigating a bug?
I need access to your Git repository (GitHub/GitLab), a detailed description of the issue, and steps to reproduce it (or a screen recording).
Do you work with both Expo and React Native CLI (bare)?
Yes, I'm highly experienced in debugging and maintaining both Expo-managed workflows and bare React Native CLI projects.
Will you explain what caused the bug?
Yes. For Standard and Premium packages, I don't just fix the code silently. I provide a clear explanation of what caused the issue and how my solution prevents it from happening again.
Can you update my outdated React Native app to the latest version?
Yes, updating deprecated libraries and migrating to the latest React Native version is a service I provide. Please message me for a custom quote depending on how outdated your app is.
