About this Gig
I build, maintain, and fix revenue-critical iOS and Android apps for founders who can't afford delays.
If your app is crashing, lagging, rejected by the App Store, or stuck halfway through development, I step in to stabilize, optimize, and deliver clean, scalable solutions. My focus is simple: keep your app fast, secure, compliant, and running smoothly.
What I Do:
* Fix crashes, bugs, UI issues, and glitches
* Optimize performance and improve loading speed
* Implement security patches and updates
* Ensure compatibility with the latest iOS & Android versions
* Add new features and enhancements
* Integrate third-party APIs (Google, Firebase, payment gateways, etc.)
* Resolve App Store & Play Store compliance issues
* Fix iOS invalid binary errors
* Provide closed testing support for Android apps

FAQ
How do we start?
Please message me before placing an order. Share your app details, current issues, and source code access so I can review and provide the best solution.
What types of apps do you fix?
I fix and maintain iOS and Android apps, including apps built with Flutter, React Native, Swift, Kotlin, Java, and Objective-C.
Can you fix apps that were developed by another developer?
Yes. I frequently work on apps built by other developers. I’ll review your existing codebase and identify issues before starting any fixes.
Do you fix App Store or Play Store rejection issues?
Yes. I help resolve compliance issues, policy violations, invalid binary errors (iOS), and Google Play publishing problems.
Can you improve my app’s performance?
Absolutely. I optimize app speed, reduce crashes, fix memory leaks, and improve overall stability and responsiveness.
Do you provide ongoing maintenance?
Yes. I offer long-term app maintenance, regular updates, and version compatibility support for both iOS and Android.
Can you add new features to my existing app?
Yes. I can implement new features, integrate APIs, add payment gateways, and expand your app’s functionality.
Do you provide source code after fixing the app?
Yes. All updated and improved source code will be delivered to you.
Support after development?
I provided support for couple of weeks after development, but if you need a support for 6 months or more, i'm available for that but we need to decide a budget first.

Maryum did an excellent job creating the screw designs — very precise, professional, and creative. Communication was smooth, and she understood the requirements perfectly. I’m very happy with the results and will definitely work with her again.
