I can help with this, I will take over both codebases, complete iOS feature parity, fix crashes and stability issues, and build the Scholar Marketplace module — registration, approval flow, live sessions, and payment split logic. For the live session access control, I will tie Zoom/Jitsi room tokens directly to verified payment records so that only paid students receive a valid join token at session start. This prevents link sharing or unauthorized access without adding a separate auth layer — keeping it lightweight while still secure. For the admin panel, I will use a simple web dashboard backed by the same Firebase instance so scholar approvals, revenue tracking, and session management stay in sync with both apps in real time. Ready to start whenever you are. Kamran

Hi there, I have read your project requirement. You need an experienced developer/team to take over your existing Android (Kotlin MVVM) and iOS (SwiftUI) app, perform testing and bug fixing, complete pending iOS features, and implement a Scholar Marketplace module with live sessions, payment flow, and admin control. We can handle the full takeover and extension with a structured approach—stabilizing the current app, ensuring feature parity across platforms, and building the marketplace module with secure payment integration, revenue split logic, and live session support (Zoom/Jitsi). The focus will be clean, maintainable code and fast delivery within your timeline. A few questions to align the execution: =============================== Which payment gateway is currently used or preferred (Stripe, Razorpay, etc.)? Is the backend already prepared for marketplace features or needs extension? Do you prefer Zoom or Jitsi for live session integration? Is there an existing admin panel or should we build it from scratch? Best Regards, Srashtasoft Team

Hi, We can take over your existing Islamic education app and complete both Android and iOS without rewriting the current system. I have a development team they are Muslim since it is an Islamic education app. We’ll start by reviewing the existing Kotlin (MVVM, Retrofit, XML) Android codebase and SwiftUI iOS project, then stabilize both apps using Firebase Crashlytics to identify and fix crashes, UI issues, and performance problems while ensuring full feature parity. Once the core app is stable, we’ll build the Scholar Marketplace module: • Scholar onboarding + admin approval • Scholar profiles + dashboards • Live session creation with pricing • Student browsing + booking flow • Payment processing with 70/30 revenue split logic • Earnings tracking + admin-controlled monthly payouts For live sessions, we’ll integrate either Zoom SDK or Jitsi depending on stability and cost efficiency, with access strictly restricted to paid users. We’ll also build a lightweight admin panel for scholar management, sessions, bookings, revenue tracking, and moderation. Deliverables: • Updated Android (Kotlin) app • Completed iOS (SwiftUI) app • Scholar Marketplace module • Admin panel • Store-ready builds • Clean handover + documentation We can start immediately and work within your 10–15 day timeline with milestone-based delivery.

Regarding your project, I have a quick question: Is there an existing backend and admin panel for managing users and content, or will the new Scholar Marketplace require building this administrative backend from scratch? My initial thought is to use a robust Python/Django backend to handle the Scholar Marketplace logic, payment processing, and revenue splitting. Django's built-in admin panel would significantly streamline the manual scholar approval and payout management you've described. I previously tackled a similar challenge in this project: https://learners-app.com. As the Lead Engineer for this ed-tech platform, I architected the backend and a custom content engine, facing complexities analogous to the marketplace and educational features you need to implement. My experience with both Android and iOS development ensures a cohesive approach to completing both apps. Let's connect to discuss the architecture. Regards, Philip O.

Hello There, Taking over an existing app is not about coding fast, it is about **understanding architecture quickly and fixing without breaking stability**. Most delays happen when developers skip this step. I understand you need rapid takeover, bug fixing, iOS completion, and a clean Scholar Marketplace module within a tight timeline. Here is how I would approach it: 1. Quick code audit (Android + iOS) to map flows, dependencies, and risk areas before changes 2. Fix crashes and UI issues with root-cause approach using Firebase Crashlytics data 3. Complete iOS features to match Android with consistent UX and performance 4. Build Scholar Marketplace with clean modules (registration, approval, sessions, pricing) 5. Integrate Zoom/Jitsi with access control for paid users only 6. Implement payment flow with 70/30 split logic and scholar earnings dashboard 7. Deliver a lightweight admin panel for approvals, sessions, and revenue tracking I am comfortable with Kotlin MVVM, SwiftUI, payment systems, and working on live codebases. Timeline: 10 to 15 days with milestones (Audit → Fixes → iOS → Marketplace → Testing). One key question: is your backend already structured to support revenue split and session control, or should that be extended? Regards VK
