I will optimize your app performance, fix lags, crashes, and anrs


About this gig
Is your Android app slow, laggy, draining battery, or getting poor Play Store vitals? I can fix those for you!
I'm an Android engineer who specializes in performance. I find the real bottlenecks using Android Studio Profiler, Perfetto, LeakCanary, and Firebase Performance, then fix them in your code.
What I can improve:
- Slow app startup (cold/warm start)
- UI jank and dropped frames (XML & Jetpack Compose)
- Memory leaks and OutOfMemory crashes
- ANRs and main-thread blocking
- Battery drain and background work
- Slow network calls and image loading
- Large APK/AAB size (R8, resource shrinking)
- RecyclerView / LazyColumn performance
- Baseline Profiles for faster launch
What you get:
- Clear audit report with evidence (traces, screenshots)
- Prioritized list of issues by impact
- Clean, tested code fixes (Standard & Premium)
- Before/after metrics so you can see the gain
Kotlin and Java supported. MVVM, Clean Architecture, Compose, Coroutines, Room, Retrofit.
Not sure which package fits? Message me before ordering with your app details and I'll recommend the best option.

FAQ
Which tools do you use to find performance issues?
Android Studio Profiler (CPU, memory, network), Perfetto/System Tracing, LeakCanary, StrictMode, Macrobenchmark, and Firebase Performance Monitoring. I always back my findings with real data.
Do I need to give you my full source code?
For the Basic audit, a read-only repository link or a ZIP is enough. For code fixes (Standard/Premium), I work on a separate branch so your main code is never touched until you approve. I’m happy to sign an NDA.
Can you guarantee a specific speed improvement?
Results depend on your app’s current state. I can’t promise exact numbers, but I measure before and after, and most apps see clear gains in startup time, memory use, or frame rate. If I find the app is already well optimized, I’ll tell you honestly.
Do you support Jetpack Compose or only XML?
Both. I handle recomposition issues, unstable parameters, LazyColumn/LazyRow performance, and legacy XML layout and RecyclerView problems.
Will you change my app’s features or design?
No. I optimize performance without altering functionality or UI unless you approve it.
Can you help reduce my app size for the Play Store?
Yes. I use R8/ProGuard, resource shrinking, image format optimization, dynamic feature modules, and App Bundle best practices.
