Senior Unity Android Developer Needed — ANR & Crash Rate Fix (Fixed Budget)

Project Overview

I develop and publish Android games using Unity. My current live game has ANR and crash rates above Google Play's acceptable thresholds, and I've had recurring stability issues across multiple projects — I suspect there may be a pattern in how I structure my Unity Android builds that's contributing to this, beyond any single bug.

Current metrics:

• ANR rate: over 1.5% (Google Play's bad-behavior threshold is 0.47%)
• Crash rate: over 1.1% (Google Play's bad-behavior threshold is 1.09%)

Engine & stack:

• Unity, built for Android
• Ad mediation: ironSource LevelPlay, with multiple ad networks connected

What I'm Looking For

I need a senior Unity Android developer to:

1. Diagnose the actual root cause(s) of my ANR and crash rates using real ANR/crash data and traces I'll provide (Play Console exports — I have data and am continuing to collect more, but I'm not strongly literate in reading these reports myself, so I'll rely on your expertise to interpret them correctly).
2. Audit my project for structural or architectural issues that may be contributing beyond any single bug — I suspect the way I build my games may have recurring patterns that cause instability, and I'd like an experienced second set of eyes on the overall project, not just a patch for one symptom.
3. Investigate whether ad mediation (LevelPlay) is a meaningful contributor. I've seen claims that a large share of ANRs in Unity Android games are tied to ad SDKs, though I have no way to verify that myself — please confirm or rule this out with real evidence from my data rather than assuming it's true.
4. Fix what's fixable, and clearly tell me what isn't (e.g. platform/OEM-level issues outside what application code can control).
5. Clean up and stabilize the project without breaking existing gameplay mechanics or functionality — the game is fully playable and live today; this is a stability and quality pass, not a rebuild.

Target

Bring ANR rate below 0.47% and crash rate below 1.09% (Google Play's official "bad behavior" thresholds).

What I'll Provide

• Unity dev project access
• Play Console ANR/crash trace exports and ongoing Android Vitals data
• Whatever additional context or access is needed once you're in the data

What I'm Not Looking For

• A fix that converts ANRs into crashes (e.g. force-closing the app) to improve one metric at the other's expense
• Changes presented as fixes without a clear, verifiable explanation of why they work
• A promise of 0% ANRs/crashes — I understand that's not realistic; I just want to get under Google's thresholds with a stable, well-explained fix

Engagement

Fixed budget, scoped to diagnosis + fix + brief written explanation of root causes found. Happy to discuss scope further based on your initial review of the data.
