The full UI for my cross-platform app is finished and lives in a clean code-base; what I now need is an experienced developer who can take that work all the way to the stores. Here is the flow I’m expecting: 1. Compile the existing source so it runs smoothly on both iOS and Android. 2. Drive a round of Functional, Performance and User-Experience testing that catches edge-cases before the review teams do. I’ll provide test accounts and any device profiles you request; you’ll supply detailed reports and fixes. 3. Once we’re green across those checkpoints, prepare the production builds, configure store assets (screenshots, descriptions, signing certificates, provisioning profiles) and guide the apps through App Store Connect and Google Play Console until they are approved and live. You will have direct access to the repo, Figma files, and my personal Slack for quick feedback loops. Success is the moment the app appears publicly with no critical or high-priority issues flagged in the first 30 days. If you have shipped polished React Native, Flutter or similar cross-platform projects before and enjoy a tight release schedule, I’d love to start right away.

Hi, I can take your finished app from repo to live listings. Step 1: compile for iOS and Android, fix build and dependency issues, and confirm it runs on the device profiles you request. Step 2: functional, performance and UX testing against your Figma, with a clear report per issue (steps, severity, screenshots) and fixes pushed to the repo. Step 3: release builds, signing certificates, provisioning profiles, privacy labels, screenshots and descriptions, then I follow the apps through App Store Connect and Play Console review until approved. Slack for quick feedback works well for me. Is the app built in Flutter or React Native? Regards, Harsh Thoriya

Hi, CnEL India can take your existing React Native app from the completed codebase through testing, production builds and store-submission preparation. Our methodology: * Review the existing React Native source, dependencies, Figma and build configuration. * Configure and compile Android and iOS builds, resolving dependency and platform issues. * Run structured functional testing across the provided test accounts and device profiles. * Test navigation, authentication, core workflows, edge cases and error states. * Perform performance and UX checks, including startup, responsiveness and resource usage. * Document issues with clear reproduction steps, severity and test results. * Fix identified issues and perform regression testing. * Prepare production Android/iOS builds with appropriate signing and release configuration. * Organize store screenshots, descriptions and required metadata from the provided assets/content. * Assist with App Store Connect and Google Play Console submission steps. * Verify release builds and address store-review issues where applicable. * Provide final QA reports, build details and release documentation. We would first audit the current codebase and build setup, then move through compile → test → fix → regression → production build → store submission in controlled stages.

For a finished cross-platform UI, I’d begin with a release-readiness audit rather than immediately generating store builds. The highest-value first step is verifying dependencies, native iOS/Android configuration, API/environment handling, permissions, signing requirements, and production-only issues before the Functional, Performance, and UX testing cycle. I’m Sumit Joshi from Sacesta Technologies. My priorities would be clean implementation and user experience. I’m comfortable taking React Native/Flutter applications through device testing, crash and edge-case debugging, performance profiling, release configuration, certificates/profiles, APK/AAB/IPA generation, and both store submission workflows. Testing would cover critical journeys, interrupted/network states, authentication/session behaviour, device sizes, loading/error states, startup/runtime performance, and regression after fixes. Issues would be documented with severity, reproduction steps, evidence, and closure status. A relevant example is JiffyJaf, where we worked across production mobile workflows, API-connected functionality, QA, and release-ready application states. I can own the process from the existing repository through App Store Connect and Google Play submission, including resolving app-related review issues within scope.

Hi, Thanks for sharing the project details. I can take your existing cross-platform codebase from the current UI-complete stage through testing, production builds, and App Store/Google Play release. I’m experienced with Flutter/React Native workflows, iOS and Android builds, signing, provisioning profiles, release configuration, QA, performance checks, and store submission processes. I would first review the repository and build environments, then resolve compilation or dependency issues and run functional, performance, and UX testing across the required device profiles. I can document defects clearly, implement fixes, prepare production builds, configure certificates and store assets, and support the submission process through approval. I’ll also check common release issues such as permissions, deep links, crashes, API/environment configuration, startup performance, and responsive behavior before submission. One question: is the current app built in Flutter or React Native, and does it already compile successfully in development mode on both iOS and Android? Best regards, Jaroslav Caprata

Your UI is done and the codebase is clean — now the real work is getting it compiled on both platforms, hardened through real testing, and live on both stores with no review rejections or launch-week surprises. I would audit the repo first (Expo or bare React Native, or Flutter) and produce clean debug builds for both platforms, then run structured functional, performance, and UX passes with detailed reports — fixing every issue I find, not just logging it. For release I would configure signing, prepare store assets, and guide the builds through App Store Connect and Play Console until they are approved. I shipped Jyotish AI, a live Android app paired with a web app, so the full path from codebase to approved store listing is familiar territory. Two quick questions: is the codebase Expo or bare React Native, and do you already have Apple Developer and Play Console accounts with certificates ready? Share repo access and I can start the compile audit the same day — no long onboarding needed.

The focus on ensuring a smooth compilation for both iOS and Android is key to delivering your app on time. I’d start by reviewing the existing codebase to identify any dependencies or configurations that might affect cross-platform functionality. Next, I’d conduct thorough functional, performance, and user-experience testing, ensuring we catch edge cases early. This includes preparing detailed reports on any issues found and fixes implemented. I’d also like to confirm your preferred tools for tracking and reporting bugs before we begin testing. Having shipped polished React Native apps before, I understand the importance of a smooth launch. What specific features or functionalities do you see as critical for the first round of testing?
