I have an existing Xamarin Forms application that already runs smoothly on iOS and Android. I now need the full codebase moved over to .NET MAUI so I can keep pace with the latest tooling and long-term platform support. While you perform the migration, I also want to introduce a handful of new features to take advantage of MAUI’s capabilities rather than simply doing a like-for-like port. Core scope The current app has about the usual mix of pages, view-models, and XAML-based UI. All functionality that works today must compile, deploy, and behave the same on iOS and Android after the upgrade, plus the agreed-upon enhancements. Any platform-specific tweaks (e.g., iOS status bar, Android permission prompts) should be handled with MAUI best practices. Key deliverables • Up...
...Optional extras: user accounts that store generation history and let people return to old designs; I’m open to your suggestions on other features that would give us an edge in my country. Technical expectations You can pick the stack—React, Vue, Svelte, or vanilla JS on the front, plus any modern backend (Node, Django, Laravel, etc.). I’m fine with either a mature QR library (e.g., , goqr, Zxing) or an API, as long as generation is instant and works offline if the API drops. CSS should be clean and accessible; responsiveness is a must. Please plan for SEO-friendly routing and analytics hooks from day one. Deliverables 1. Source code in a public or private repo with commit history. 2. Deployed, SSL-secured site ready for traffic. 3. Admin notes covering...

...iPad. The goal is a seamless, touch-friendly version that preserves every existing workflow while taking advantage of iPadOS capabilities. Your task • Review the present SQL Server schema, stored procedures, and any helper scripts. • Design and build an iPad solution that connects securely to the same data set, whether through a native Swift/Objective-C app, a .NET-based wrapper (e.g., Xamarin or .NET MAUI), or a well-optimized web front end—whichever you can justify as the most stable and maintainable. • Implement offline caching for spotty connections and ensure real-time sync when the device comes back online. • Handle authentication/authorization identically to the desktop version so user roles carry over without rewriting our security mod...
I’m looking for an experienced Kalipso Studio developer to build an Android app whose first goal is simple: let warehouse staff count and record stock quickly and accurately. The initial milestone is an MVP that: • Opens straight to a clean “New Count” screen. • Lets users add items manually or by barcode scan (ZXing or Kalipso’s native scanner component). • Saves each entry—item code, description, quantity, date/time—locally and sync-ready. From there, I want to grow the app in short, progressive sprints. Next stages will include: – Role-based access (admin, supervisor, custom roles I can create myself). – Basic history view so I can review past counts. – Optional cloud sync / simple report export...
...Android and iOS tablets. • Barcode types: UPC and EAN only; no QR handling is required. • Result view: display product name, SKU, image and price pulled from our website or API endpoint directly in the app (no browser redirect). I’m open to React Native, Flutter, or any comparable cross-platform framework as long as startup time is fast and the camera scanner feels snappy (libraries such as ZXing or ML Kit are welcome). External scanner input should be treated the same as camera input, auto-submitting on the final line-feed. Deliverables 1. Source code with clear build instructions. 2. Signed release builds for Android (APK/AAB) and iOS (TestFlight or IPA). 3. Brief setup document outlining how to point the app to our staging and production URLs. 4. ...
I’m rolling out a batch of And...documentation into a working, repeatable process. Here’s what I’m expecting: • A small, clean Android Studio project (Java or Kotlin) that demonstrates the full QR-based provisioning flow and installs my DPC as the Device Admin / Device Owner on Android 8+. • A concise snippet or script that generates the correct QR payload (package name, download URL, admin extras, etc.)—feel free to use ZXing or any other generator as long as it’s open source. • Step-by-step notes so I can recreate the QR and re-flash devices without your assistance. I’ll confirm completion by factory-resetting a device, scanning the code, and seeing my app land in Device Admin with no manual setup. If you can get me to tha...

I have a collection of Java / Kotlin classes that sit at the heart of my Android app. They manage in-memory data structures, expose that data to the rest of the app, and synchronise it with our back-end through a handful of REST-style APIs. I now need the exact same behaviour expressed in clean, idiomatic C# so the project can be compiled under the .NET Android toolchain (Xamarin or MAUI—whichever you prefer). Your task is to translate every class, interface, and public method signature to their .NET equivalents, preserving naming, access levels, and logic while embracing C# conventions such as properties, async/await, and nullability annotations. The resulting code must build and run in Visual Studio, target current Android SDK levels, and integrate with the existing API end...
...________________________________________ Core functionality • Built-in barcode scanner (no AI, no photo recognition) • Food data lookup via Open Food Facts • One results screen only • Simple, rule-based logic (no AI) Important: Barcode scanning must be available to all users without paywalls, additional downloads, or per-scan charges, using a standard on-device Android barcode library (e.g. Google ML Kit or ZXing). What is NOT included (out of scope) • iOS version • User accounts or login • Subscriptions or payments • Food comparisons or alternatives • Deep-dive explanations • Personalisation • Analytics dashboards • Food images • Animations or complex UI If you propose any of the above, they are out of scope for...

For the first release, supporting the common QR Code standard is fine, yet please structure the parser so adding Data Matrix or Aztec later is straightforward. Tech stack and expectations • Flutter (latest stable channel) with null-safety • Camera & decode handled through a well-maintained package such as qr_code_scanner, zxing, ML Kit, or another option you propose • Scan works on both Android and iOS with proper permission handling • Parsed fields automatically populate the existing transfer form without breaking my current validation logic • Clear error messaging if a code is unreadable or lacks required data Acceptance is simple: open the transfer screen, tap the sc...
Our mobile app is in production; I now need a focused set of improvements completed: • Local data must be stored seamlessly when the connection drops, then pushed to the server automatically the moment the device reconnects. No manual triggers—users should never notice they were offline. • A compact dashboard page showing overall student performance (simple charts or progress indicators are fine) has to be added to the teacher section. Data sources and existing view-models are already in place. • Teachers also need a dedicated Attendance report. A clean list or table view filtered by class/date will do; exporting or printing is not required at this stage. • Replace the current username/password screen with Google Authenticator sign-in. If you prefer Firebase,...

...Windows. The new app must behave identically to the existing one, so two core capabilities have to make the jump with zero regressions: • Push notifications – keep the same Firebase/APNs flows, badges, and deep-link handling. • Full Bluetooth support – both classic SSP (for legacy serial-port exchanges) and BLE (for modern GATT reads/writes and device scanning). I will hand over the entire Xamarin repo, current notification keys, and the Bluetooth service specs. I expect the MAUI project to build and run from Visual Studio 2022, produce signed packages for Android (AAB), iOS (IPA/TestFlight), and a Windows MSIX, and to follow best practices for dependency injection, platform-specific handlers, and Blazor component structuring.
