I have a production-ready .NET MAUI app that runs on both iOS and Android. At the moment its data layer relies on Realm Sync to keep the local store and our backend in lock-step, giving users true real-time data synchronization. Realm is being phased out of our stack, so I need that entire sync layer replaced with Power Sync while retaining the same instant, bidirectional behaviour. Key points you should know before diving in: • The current logic, repositories, and data models are already cleanly separated, so you will mostly be swapping out the sync engine rather than refactoring the whole domain layer. • Real-time data synchronization is non-negotiable; users expect changes made on one device to appear on another within seconds. • All sync requests must respect our existing user authentication flow (JWT tokens issued by our .NET backend). There are no extra encryption or access-control requirements beyond what Power Sync already supports. • The work must compile and run on both target platforms with no conditional-compilation hacks. Please deliver: 1. Updated MAUI project integrating Power Sync with real-time sync and auth hooks wired in. 2. A brief migration guide (markdown is fine) explaining new services, configuration, and any code-first steps another developer would need to follow. 3. A test build for iOS (IPA) and Android (APK/AAB) demonstrating successful sign-in and cross-device live updates. I’m looking for someone who has at least five years of hands-on MAUI/.NET mobile experience and can move quickly without a lengthy learning curve. If you’ve already integrated Power Sync, even better—tell me about it when you bid.

Hi, I can help migrate your existing .NET MAUI app from Realm Sync to PowerSync while preserving the same real-time, bidirectional synchronization behavior across both iOS and Android. Since your repositories and domain layer are already cleanly separated, this migration can be handled efficiently with minimal disruption to the existing architecture. What I can deliver: • PowerSync integration with real-time sync support • JWT authentication flow wired into sync requests • Cross-platform compatibility for iOS & Android • Updated MAUI project with clean implementation • Migration/setup guide for future developers • IPA + APK/AAB test builds demonstrating live sync I’m experienced with: • .NET MAUI & C# • Offline-first mobile architectures • Real-time synchronization systems • Secure API/auth integration • Production mobile deployments A few quick questions: ===================== Which local database are you planning to pair with PowerSync? Is your backend already exposing PowerSync-compatible endpoints? Approximately how many synced entities/collections are involved? Do you require conflict-resolution logic beyond last-write-wins? I can move quickly on this migration and ensure a stable transition away from Realm without impacting the user experience. Best regards

Hi, Can you share more about your current architecture, specifically how the data models are structured? I’d love to dive deep into the specifics of your existing setup. With over 5 years of experience in .NET MAUI and mobile development, I can efficiently replace Realm Sync with Power Sync, ensuring that real-time, bidirectional data synchronization remains intact. I’ll implement the necessary authentication flows using your JWT tokens while adhering to the existing structure without any messy hacks. I will also provide a migration guide detailing the new services and configurations, along with a test build for both iOS and Android to demonstrate successful sign-in and live updates. Let me know if you’re ready to move forward! Best, Manoj

Hello, I am a full-stack UI/UX and frontend developer with 5+ years of experience building interactive canvas-based applications, beauty-tech tools, and AI-assisted editing interfaces. I specialize in improving real-time image manipulation systems with smooth performance, realistic visual output, and clean user experience design. For your PMU consultation preview app, I will enhance both realism and usability by improving overlay rendering, refining blending techniques, and optimizing canvas-based controls for smooth drag, resize, and rotation without artifacts. I will focus on creating natural eyebrow, lip blush, and eyeliner simulations using improved transparency, feathering, and texture mapping to achieve a more realistic “healed PMU” effect. I will also implement symmetry guides, face mapping improvements, and optional AI-assisted recommendations to elevate consultation accuracy. On the UI side, I will clean up transform handles, remove visual artifacts, and upgrade the interface to a premium, luxury beauty app aesthetic optimized for mobile responsiveness. My approach is practical and product-focused—enhancing your existing prototype rather than rebuilding it—so we achieve a polished, production-ready experience quickly. I would be glad to collaborate and refine this into a high-end PMU preview tool.
