I will optimize your mobile app performance and fix bugs
About this Gig
I will fix bugs, improve performance, and integrate AI into your Flutter, iOS, or Android app.
Is your app slow, crashing, difficult to maintain, or missing the features users expect? I help founders and teams turn unstable apps into fast, reliable products that are ready to grow.
What I can help with:
- Fix Flutter, iOS, and Android bugs and crashes
- Improve startup time, scrolling, memory use, battery use, and API performance
- Review app architecture and clean up difficult code
- Build or improve UI, animations, forms, payments, and customer flows
- Integrate AI chat, AI assistants, OpenAI-compatible APIs, and custom AI workflows
- Add analytics, error monitoring, feature flags, and performance tracking
- Prepare app-store listings, onboarding, analytics, and retention improvements to help attract and understand real users
- Review your app and provide a practical improvement plan
I focus on clean code, clear communication, and real results. I will first understand the issue, explain the plan in plain language, and keep you updated as work progresses.

FAQ
What do you need from me to get started?
Access to your code (GitHub/GitLab invite or a zip), a short description of the bug or slowdown with steps to reproduce, and a screenshot or screen recording if you have one. For store issues, add me to your developer account as a team member.
Which platforms and languages do you work with?
iOS (Swift, SwiftUI, UIKit), Android (Kotlin, Java), Flutter (Dart) and React Native (JavaScript/TypeScript), plus Firebase and common backends. If your stack is different, message me and I'll tell you honestly if I'm a good fit.
What if you can't fix my bug?
Message me before ordering so I can review the issue and confirm I can fix it. If I can't fix a bug we agreed on, you get a refund for it. If a bug I fixed comes back, message me and I'll look at it right away.
Can you also add AI features to my app?
Yes. I integrate OpenAI, Claude, Gemini and on-device AI into iOS, Android and Flutter apps: chat assistants, voice, and smart automation. See my AI integration gig or message me for a custom offer.
How quickly can you start?
Usually the same day. I'm US-based and reply fast, so send me the issue and I'll tell you what's wrong and how long the fix will take before you order.
