About this gig

Is your app stuck in "Rejected" status or crashing on the latest OS? Don't risk your launch with a junior developer.


With 8 years of experience and 200+ apps deployed, I specialize in "rescue missions." I fix the complex bugs, broken SDKs, and policy violations that others can't. Whether it's a Stripe payment failure, a Branch.io deep link loop, or a strict Apple/Google rejection, I will get your app back on track.


What I Solve:

  • Store Rejections: Fixing Guideline 4.0 (Design), 5.1.1 (Data Collection), or technical crashes.
  • SDK Upgrades: Seamless updates for Firebase, Stripe, Revolut, IDverse, and PubNub.
  • API & Backend: Fixing broken REST APIs, JSON parsing errors, and Auth loops.
  • Performance: Resolving memory leaks, slow UI rendering, and Lottie animation lag.
  • Critical Fixes: Deep linking (Branch.io), Maps API, and Biometric auth issues.

My Process:

  1. Audit: I pinpoint the exact root cause of the crash or rejection.
  2. Repair: Clean, modular code fixes that follow 2026 best practices.
  3. Validate: Rigorous testing on physical iOS/Android devices.
  4. Deploy: Guidance on resubmission to ensure 100% approval.
