Hi there, I can build your file-sharing app for both Android and iOS with a secure sign-up, 2FA login, profile management, and seamless peer-to-peer file transfers over Wi-Fi Direct, Bluetooth LE, and fallback Bluetooth. Although I have delivered similar features in other apps, I haven’t built a full SHAREit-style tool yet, but I’m confident I can implement it end-to-end with clean, well-documented code. I will also set up the back-end for auth, profiles, and transfer history, and provide a full hand-off with build instructions and a short walkthrough video. I would request we connect once to discuss your requirements in details. Kindly ping me to once you are available. Thanks, Rahul A.

Hello, I can deliver the full source code for both platforms, the configured backend, clear build/run documentation, and a short video walkthrough demonstrating 2FA login, device discovery, and a successful encrypted file transfer between two phones. I have 10+ years of experience on mobile applications ( Android +iPhone/ iPad ) and App admin with development web services where admin can manage the app from the back end, I have developed the TAXI apps, google map, Event App, Job Portal App, Restaurant App, Dating App, Social chat with video calling and other apps with clients need * I am familiar with android/IOS applications for both native and hybrid apps. Thank's, Shivpal S

@kamran2012

Hello, I will develop a secure, high-performance file sharing app for both Android and iOS that delivers the same convenience and reliability as SHAREit, with a strong focus on privacy, encryption and smooth user experience. I will implement a complete sign-up and login system with profile storage and mandatory two-factor authentication, while still allowing email/password and one tap Gmail sign-in for ease of use. I will build the app so users can manage their preferences, view complete per contact file sharing history, resume interrupted transfers and re-send files quickly. The connection system will intelligently switch between Wi-Fi Direct and Bluetooth LE, with fallback to classic Bluetooth only when required and all transfers will be encrypted end to end for full security. I will ensure native level performance using Flutter or native stacks as needed, deliver clean and well documented code through a private Git repository with CI/CD setup and configure a simple Firebase or Supabase backend for authentication, profiles and history storage. You will also receive full source code, setup documentation and a short walk through video showing login with 2FA, device discovery and a successful file transfer between two phones. Looking forward to discussing further. Best regards, Kamran

Core features include: • User preferences (dark mode, notifications, default folder) • Per-contact file sharing history with timestamps & quick re-send • Resume interrupted transfers • Intelligent switching between Wi-Fi Direct, BLE, and Bluetooth fallback • End-to-end encryption for all transfers • Clean, well-documented code with private Git repo & CI/CD • Firebase or Supabase backend for auth, profiles, and history Deliverables: Android & iOS source code, backend setup, documentation, and demo video. Lets have a chat and discuss more in detail. Best Regards, Sumay Infotech

@vipinjain1213

Hello!! This is a performance-critical peer-to-peer file transfer app. The core risks are connectivity switching, encryption, and transfer recovery — not UI. I will build this as a peer-first system where files never touch the backend and all transfers are encrypted end-to-end. Approach • Flutter app with platform-specific native modules for Wi-Fi Direct and Bluetooth • Firebase or Supabase used strictly for authentication, profiles, 2FA, and history • Mandatory two-factor authentication enforced at every login • Connection priority: Wi-Fi Direct → Bluetooth LE → Bluetooth fallback • Encrypted transfers with resumable chunks and integrity checks • Per-contact transfer history synced to the user profile • Preferences stored locally and synced on login The Flutter layer will handle UI and flow consistency. Native channels will handle discovery and transport to maintain native-grade performance. CI/CD will be configured for TestFlight and Play internal tracks. Code will be delivered through a private Git repository with setup docs and a short walkthrough covering login, discovery, and a completed transfer. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Please connect over chat so we could discuss the details.

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Secure Cross Platform Peer to Peer File Sharing With Mandatory 2FA ))⚜⭐⭐⭐⭐⚜ What makes your idea compelling is the emphasis on security and reliability alongside SHAREit level convenience. Mandatory two factor authentication, encrypted transfers, and seamless resume place this firmly in a professional grade category rather than a casual utility. You are looking for a native quality Android and iOS app that handles secure onboarding, strong authentication, smart device discovery, and fast peer to peer transfers using the best available connection method. Clean code, CI CD readiness, and a simple backend for profiles and history are clearly important for long term ownership. I have over 9 years of experience delivering cross platform mobile systems that combine real time data transfer, secure authentication, and production ready pipelines. I focus on architecture that keeps performance high while making future updates straightforward. My approach would be to lock down auth and encryption first, then build a resilient transfer layer with intelligent fallbacks and full session recovery. Three key features I would focus on: • Mandatory two factor authentication with secure profile storage • Encrypted peer to peer transfers with Wi Fi Direct and Bluetooth LE switching • Per contact transfer history with resume and re send support I would be glad to review your benchmarks and outline a clear delivery plan and milestones. Warm Regards, Farhin B.

@mahig47

Hello! As per your project post, you are looking to build a cross platform peer to peer file sharing mobile application similar to SHAREit for both Android and iOS, with a strong focus on security, seamless transfers, and native level performance. The goal is to deliver a reliable app that allows users to securely sign up, authenticate with mandatory two factor verification, discover nearby devices, and exchange files. My focus will be on delivering a high performance mobile application with a secure authentication flow, intelligent connection switching, and a smooth user experience on both platforms. Users will be able to register with name, profile photo, email, and phone number, manage personal preferences like dark mode and notifications, view per contact file sharing history with timestamps. I specialize in building secure, scalable mobile applications using Flutter for cross platform consistency or native Kotlin and Swift when required for low level performance. I have strong experience with Firebase or Supabase for authentication, two factor flows, and structured data storage, along with CI CD pipelines for TestFlight and Play Store internal releases. My focus will be on clean architecture, well documented code. Let’s connect to review performance expectations, platform preferences, and delivery milestones so we can build a fast, secure, and future proof peer file sharing platform. Best regards, Nikita Gupta.

@avinashjain09

I can build this SHAREit-style app with the reliability and security you’re asking for. The biggest pain points in P2P transfer apps are unstable discovery, interrupted transfers, and weak security/identity—so I’ll focus on fast connection switching, resumable transfers, and a strict 2FA login gate from day one. What I’ll deliver: • iOS + Android apps with native-quality performance (Flutter or React Native is fine, but Wi-Fi Direct/BLE works best with platform channels or native modules). • Secure signup storing name/photo/email/phone in Firebase. • Login with email/password or Google sign-in plus mandatory 2FA (OTP/email or authenticator). • Preferences screen (dark mode, notifications, download folder). • Per-contact transfer history with timestamps + quick re-send. • Robust resumable transfer logic (chunking + checksum + auto-retry). Connection + security: • Intelligent switching between Wi-Fi Direct and Bluetooth LE, fallback to classic Bluetooth only when needed. • End-to-end encryption for every transfer (AES-GCM + secure key exchange). If you want a transfer app that feels fast like SHAREit but is secure and stable, I’m ready to start and share similar work/prototypes.

@utamshingala
