I have a production-ready mobile application that runs on both iOS and Android, but a handful of functionality bugs are undermining the user experience. I need those issues tracked down and resolved first, then I want to integrate Stripe and Apple Pay so users can complete in-app purchases seamlessly. Once everything passes review, the final step is publishing the updated builds to Google Play and the App Store. You will receive the full source code, existing build files, and store-listing credentials. Please test thoroughly on real devices, confirm that payments process in sandbox and live modes, and handle any store-side compliance tweaks that appear during submission. Deliverables • Bug-free iOS & Android builds • Fully working Stripe and Apple Pay flows (sandbox + live) • Apps approved and live on both stores, with version notes reflecting the updates Acceptance criteria will be met when the live listings match the delivered builds, payment transactions succeed end-to-end, and no functionality bugs are reproducible.
