About this gig

Are payment failures, broken subscriptions, incorrect attribution, or Superwall configuration issues preventing your app from generating revenue? I specialize in identifying and fixing complex mobile monetization problems quickly and efficiently.


Whether your app uses Stripe, RevenueCat, Google Play Billing, Apple In-App Purchases, AppsFlyer SDK, or Superwall, I will troubleshoot the root cause and deliver a reliable solution. I resolve checkout failures, purchase validation errors, subscription bugs, SDK initialization problems, event tracking issues, conversion attribution errors, paywall display problems, API connection failures, webhook errors, and authentication issues.




What you can expect:


  • Fast bug diagnosis
  • Clean and maintainable fixes
  • Accurate AppsFlyer attribution
  • Proper Superwall integration
  • Secure payment workflow
  • Thorough testing before delivery
  • Clear communication throughout the project


If your app is losing revenue because of payment, tracking, or subscription issues, send me a message before ordering and I'll help restore everything quickly and professionally.
