I already have working website and need a Android and iOS builds for my e-commerce platform, Idrink.in. What I now need is a clean upgrade of both codebases to the latest stable versions of their respective frameworks and SDKs, followed by successful re-submission to Google Play and the App Store. The existing UI/UX is staying exactly as it is, so your effort will centre on technical migration, dependency updates, compliance with the newest store policies, and resolving any deprecation warnings that appear during the process. Because the core shopping flow, payment gateway integrations, and push-notification services are already in place, I expect the project to unfold in three straightforward stages: • Codebase upgrade for Android and iOS, ensuring backward compatibility with current features • Internal QA build delivery so I can test the refreshed apps end-to-end • Final store submissions, with approval confirmation screenshots or links You’ll receive the current source code, signing certificates, and existing store listings as soon as we start. I’m happy to answer any technical questions quickly so we keep momentum.

Hi, A clean SDK/framework upgrade that clears Play Store + App Store review on the first attempt is a migration-discipline problem — and it's exactly the kind of work we run regularly on live ecommerce apps. Since your shopping flow, payments and push are already working, I'd keep the scope tight and risk-free: - Android + iOS codebase upgrade to the latest stable framework/SDK versions, preserving every current feature and your UI/UX exactly as-is - Clear all deprecation warnings and align with the newest store policies — target SDK, privacy manifests, updated signing requirements - Internal QA builds delivered for your full end-to-end testing before anything ships - Final submission using your existing signing certificates and store listings, with approval links/screenshots confirmed We ship ecommerce apps on both stores ourselves — JiffyJaf (Android + iOS), JJ Milk, Mohollla — so store-review compliance and re-submission are familiar ground, not a learning curve. No regression bugs introduced: I personally verify the refreshed builds against your current feature set before handover, so the upgrade stays invisible to your users. One question to scope it right: what are the apps currently built in — native (Kotlin/Swift), Flutter, React Native, other — and which framework versions are you on now?

Hi! Idrink already has the tight ecommerce flow done — the upgrade is straightforward: bump frameworks/SDKs, clear deprecations, re-sign, and re-submit to both stores under the current policy without touching the UI/UX. We've done this dance recently for two India-based ecommerce apps — one on React Native (target SDK 34 + iOS 17), one native Kotlin + Swift. The pieces that usually need attention are payment gateway SDK compatibility and re-validating FCM/APNs on the new target SDK before the QA build goes out. Plan: 1. Per-platform dependency audit + upgrade with backward compatibility checks 2. Internal QA builds (debug + release) for you to test end-to-end 3. Store submission with approval screenshots/links Quick check — is the current codebase React Native, Flutter, or fully native (Kotlin + Swift)? Ping me here and we can lock the SDK targets and timeline. — Rohan

The main risk here is not changing the UI, but upgrading Android/iOS dependencies, SDKs, signing, payment flow, and push notifications without breaking the existing e-commerce experience. I would start by reviewing the current mobile source code, framework versions, third-party packages, store rejection history if any, and the current Google Play / App Store requirements. Then I would upgrade the Android and iOS codebases step by step, resolve deprecation warnings, rebuild the apps, and test the core flows: product browsing, cart, checkout, payment gateway, push notifications, login, and order-related screens. I have worked on mobile app upgrades, store resubmissions, payment integrations, push notification setup, dependency updates, and release builds for both Android and iOS. Since your UI/UX should remain exactly the same, I would avoid unnecessary redesign work and focus only on migration, compatibility, QA builds, and successful submission. I would deliver internal test builds first so you can verify the full shopping flow before final submission. After approval, I would handle the store upload process and provide confirmation screenshots or links once submitted. Which technology is the current app built with — Flutter, React Native, native Android/iOS, or a WebView-based app? Thank you Mykola Sagin

Hi, Some technical que first: Q. Is the app built with Flutter, React Native, or native Android/iOS? Q. Are there any current Play Store or App Store rejection issues that need to be addressed? I can help upgrade your Android and iOS applications to the latest stable versions, resolve dependency and SDK issues, ensure compliance with current store requirements, and handle the complete Play Store and App Store resubmission process. For implementation, I’ll first upgrade the codebases and dependencies while preserving the existing UI/UX, then deliver QA builds for testing before proceeding with final store submissions and approvals. Please share the source code and I'll start right away. Warm Regards, Priyanshu
