I already generated an initial codebase with Claude—part React-style JSX components and part .NET MAUI C#. It runs, but the AI left several inconsistencies and half-wired features. I now need an experienced developer to step in, clean things up, and turn the concept into a fully functional mobile application for both iOS and Android with working in-app purchases. Scope of work • Audit the existing JSX and MAUI code, document gaps, and refactor where needed so the two layers work together smoothly. • Implement, test, and sandbox-verify in-app purchase flows on both platforms, then prepare the production configuration. • Handle standard mobile essentials—build configs, signing, store-ready assets—so I can submit directly to the App Store and Google Play. • Deliver a clean, compile-ready repository with comments and a short README describing build steps and any third-party libraries used. and launce the app for me Ownership & confidentiality I will provide a simple mutual NDA at kickoff. At final hand-off you transfer 100 % ownership of all code, assets, and build scripts to me, and send the full repository (no obfuscation or minification of source). No portions of this work may be reused or published elsewhere without my written consent. Acceptance criteria 1. The code compiles without error in Visual Studio / Xcode / Android Studio using the supplied README. 2. In-app purchases pass Apple/Google review in their respective test environments. 3. Final source and project files are delivered, and the signed NDA & IP transfer are complete. If this stack is in your wheelhouse and you’re comfortable signing the NDA, let’s get started.

Hi, The main risk is the mixed React-style JSX and .NET MAUI structure becoming difficult to maintain and unreliable to build. I would start with a full audit of the UI and MAUI layers, fix broken boundaries, and ensure the app compiles cleanly on both iOS and Android. My first priority would be codebase review, build/error resolution, and validating the in-app purchase flow in sandbox on both platforms. I’d also tighten signing, release configuration, and store-ready assets so the repository is stable in Visual Studio, Xcode, and Android Studio, with a clear README for handoff. I can keep the source clean and fully transferable under your NDA/IP terms. I have experience with mobile app debugging, cross-platform build issues, and purchase flow troubleshooting. One quick question: are the in-app purchases consumable, non-consumable, or subscription-based, and are the App Store Connect and Google Play product IDs already set up? I can review this via Freelancer chat or video call, available 11 AM–8 PM IST. Please share the repo or current build details, and I can get started right away. Regards, Ghanu & Samir KESHAV INFOTECH

Hi — Elias here from Miami. I see you're working on a cross-platform purchase-enabled app, and it sounds like you’ve made a good start with your initial codebase. One challenge with projects like this can often be integrating the back end smoothly with your front-end components. If the communication between these parts isn’t handled well, you might run into issues with performance or data handling. Another common issue is ensuring that the app functions well across different devices and platforms. Bugs can easily slip through if testing isn’t thorough, especially with purchases involved. My approach would be to first review your existing code to identify potential bottlenecks and then set up a solid testing framework early on. This way, we can catch issues before they escalate. Could you share what specific functionalities you want to prioritize for the purchase flow? Also, do you have a preferred way of testing across devices, or are you open to suggestions? Looking forward to your thoughts.

Good to see this project, Cleaning up AI-generated code that mixes React JSX with .NET MAUI is a specific kind of mess I know well. The biggest issue is usually the data binding layer between the two, where the AI wires state in JSX patterns that MAUI simply ignores at runtime. I will audit both layers, document every gap, and refactor them into a single coherent architecture. Then I will implement and sandbox-verify the in-app purchase flows on both iOS and Android, handle signing and store-ready configs, and deliver a compile-ready repo with a clear README. I will also handle the App Store and Google Play submissions for you. I will test everything on staging builds before touching production configs, so nothing breaks during review. Ready to start whenever you are. Kamran

Hi there, First of all, hats off to you for generating the initial codebase with Claude—that already saves a significant amount of development time. And yes, it's very common for AI-generated projects to have inconsistencies, duplicated logic, incomplete integrations, and disconnected flows when multiple technologies like JSX and .NET MAUI are involved. That's exactly what I'll help you resolve. I am ready to sign the NDA. Once you share the existing code, I will first audit everything, identify the gaps, complete the missing flow, implement the in-app purchases, and prepare the app for both App Store and Play Store. I also use Claude daily, so wherever it genuinely helps speed up development, I'll use it—but everything will be properly reviewed, tested, and production-ready. Once everything is completed, I'll hand over 100% ownership of the source code, assets, build scripts, and documentation exactly as mentioned in your requirements. I am a senior software developer and have delivered multiple production applications using AI-assisted development, which you can check from my profile. If this fits well with what you're looking for, I would request we connect once so I can review the current codebase and provide a clear roadmap, timeline, and effort estimate. Thanks, Rahul A.

I see you need to transform your AI-generated .NET MAUI codebase (React-style JSX + C#) into a fully functional cross-platform app for iOS and Android with working in-app purchases, handling all inconsistencies, completing half-wired features, implementing store-ready builds with signing, and launching the app while transferring 100% ownership under NDA. My mobile development approach: I'll start with a comprehensive audit of your existing JSX and MAUI C# code to identify architectural inconsistencies, incomplete integrations between the JSX UI layer and MAUI backend, and document all gaps. I'll refactor the data flow to ensure the React-style components communicate properly with the MAUI handlers, fixing any broken bindings or event propagation issues. For in-app purchases, I'll implement platform-specific IAP handlers using MAUI's dependency service pattern. On iOS, I'll integrate StoreKit 2 with proper transaction validation, receipt verification, and restore purchases functionality. For Android, I'll use Google Play Billing Library v5 with acknowledgment flows, subscription management if needed, and offline purchase validation. Both implementations will be sandbox-tested thoroughly before I configure production endpoints with your App Store Connect and Google Play Console credentials. Muhammad Saad

Hi, I can step in and clean up the AI-generated codebase, stabilize the app, and prepare it for iOS/Android release with working in-app purchases. The first thing I would do is audit the current JSX and .NET MAUI/C# structure to identify what is actually wired, what is duplicated, and what needs refactoring. AI-generated mobile code often runs initially but leaves problems around state flow, platform-specific services, build configuration, package references, signing, and store integrations, so I would clean those areas before pushing into IAP testing. For in-app purchases, I would configure and test the sandbox flows for both Apple and Google, including product IDs, purchase handling, restore flow where needed, entitlement/state updates, and basic failure cases. I can also help prepare production configuration, signing, store-ready assets, and submission steps, assuming your Apple Developer and Google Play accounts are available. I’m comfortable signing an NDA and IP transfer agreement, and I’ll deliver a clean compile-ready repository with comments, README build steps, third-party library notes, and handoff guidance. My suggested process is: code audit, stabilization/refactor, IAP implementation, platform builds, sandbox testing, store preparation, and final handoff/submission support.

It sounds like you're at the stage where the concept is proven, but the AI-generated code needs a real engineering pass before it can be shipped. The first thing I would do is audit the existing JSX and .NET MAUI layers to identify where the UI, business logic, and platform-specific code have drifted apart, then create a cleanup plan before adding anything new. That usually saves a lot of time compared to patching issues one by one. After that, I’d focus on the in-app purchase implementation and verify the entire purchase lifecycle in Apple’s Sandbox and Google’s test environment, including restoration, cancellation, failed transactions, and edge cases that often cause review rejections. Once the app behavior is stable, I’d handle signing, build configurations, store assets, and prepare release-ready builds for both platforms. I’ve worked on several applications that required taking over partially completed codebases, refactoring them into maintainable projects, and guiding them through store submission. I’m also comfortable signing the NDA and transferring full ownership of all deliverables. One question: are the current IAP products already created in both developer consoles, or do those need to be configured as part of the work? I'm ready to start reviewing the codebase.
