About this gig

Is your Android app crashing, freezing, or throwing errors you can't figure out? I'll find the root cause and fix it fast and clean.


I'm Kailash, an Android developer experienced in Kotlin and Java, with hands-on work across fintech, ride-sharing, food delivery, and e-commerce apps.


WHAT I FIX

- App crashes and ANRs (App Not Responding)

- Build/Gradle errors and dependency conflicts

- UI bugs (layout issues, RecyclerView glitches, Compose state bugs)

- Firebase/API integration errors

- Memory leaks and performance issues

- Logic errors and unexpected app behavior


HOW I WORK

1. Share your project (source code or Play Store link + error logs)

2. I review the code and reproduce the issue

3. I fix it and explain what caused it

4. You get a clean commit/patch + short explanation


TECH STACK

Kotlin, Java, Jetpack Compose, XML Views, MVVM, Firebase, Retrofit, Room DB, Android Studio, Logcat/Crashlytics debugging


WHY WORK WITH ME

- Certified by Meta, JetBrains, and Google

- Clear communication I explain the fix, not just apply it

- Fast turnaround on small-to-medium bugs

- Comfortable working inside existing codebases, not just my own
