About this gig

Is your Android app crashing, losing ad revenue, or is a broken AI feature costing you users? I fix exactly this.


On a production app with 𝟱𝗠+ 𝗱𝗼𝘄𝗻𝗹𝗼𝗮𝗱𝘀, I took crash-free rate from 73.6% to 98.7%, fixed critical AdMob revenue issues, and shipped AI features (text/image-to-video) via a custom backend. Also fixed crashes, AdMob, and added AI generation on a 500K+ download app.

Crashes, ANR & startup errors

Crashlytics diagnosis & crash-free rate
