@vijaydvaswani

Hello I’ll build a clean 1-to-1 video call and screen share MVP using .NET MAUI for iPhone, iPad, and Android. It will include stable two-way video/audio, screen sharing by either user, email-password login, idle timeout, and a simple call UI (video, mic, share, hang up). Using WebRTC with a self-hosted signaling server, it avoids recurring fees and supports free scaling. Deliverables: full source code, setup notes, and a brief doc explaining the video stack, timeout flow, and cost trade-offs — ready for App Store and Play Store submission. Thanks

@malikabdulbasit3

Being a seasoned Flutter Developer with expertise in Android, iPhone, and cross-platform mobile app development, I am perfectly poised to bring your vision for this MVP to life. My work in developing feature-rich apps that integrate diverse aspects such as Firebase and REST API – essential for this project - means I am fully adept at the technicalities of cross-platform applications. Additionally, my fluency in real-time data handling is pertinent to achieving your goal of a clean one-to-one connection with stable two-way video and audio. Moreover, my proficiency extends beyond mobile development as I can also design and deploy AI-powered automation agents to streamline business workflows – a skill that could be useful in future iterations of this project as well. These agents enhance user experiences and generate actionable insights. If given the chance, I can leverage these tools to make your video call app not just minimalistic but intelligent too. Above all, my goal aligns with yours precisely: an on-point MVP that’s lean yet reliable. It’s a challenge that I’m enthusiastic to take on, leveraging WebRTC or Jitsi - concrete zero-cost options we can consider together - or even spinning up a lightweight self-hosted signaling server on Node, Python or Go if necessary. Let's connect - no fees attached!

@jagratip3

Dear Hiring Manager, I’m ready to build your lean, cross-platform video-call MVP in .NET MAUI, supporting iPhone, iPad, and Android with stable one-to-one video, audio, and screen sharing. Approach: Video & Screen Share: Leverage WebRTC for free, peer-to-peer video and audio streaming. For screen sharing, I’ll implement platform-specific capture APIs integrated into WebRTC, ensuring immediate visibility for the other participant. Authentication: Simple email/password sign-up and login with SQL Server backend; session timeout auto-logs idle users. Cross-Platform Build: Using .NET MAUI, I’ll deliver a single codebase for iOS and Android while adhering to App Store and Play Store guidelines. Zero-Cost Infrastructure: WebRTC avoids recurring fees; if signaling is needed, I propose a lightweight Node.js server deployable on a low-cost VPS, fully self-hosted. UI/UX: Minimal interface: login screen, call screen with buttons for video, mic, screen share, and hang-up. Clean, intuitive, and focused on reliability. Documentation: Build/run instructions, architecture notes on video stack, screen sharing, and session management, including trade-offs of free/self-hosted solution. This setup ensures a fully functional MVP that “just works,” scalable for future enhancements while remaining cost-efficient. Best regards,

Hi Aharon, I'm excited about your project for a cross-platform video call app. I understand the need for a straightforward MVP that focuses on reliable one-to-one connections. With over six years of experience in mobile app development, I have a solid background in using .NET and C# Maui to build high-quality applications. I can implement stable two-way video and audio communication on iPhone, iPad, and Android, ensuring that both users can see each other and share screens smoothly. To meet your core needs, I will: • Set up email-and-password authentication without social or phone options. • Implement a session-timeout mechanism for idle users. • Deliver a minimal UI that allows easy access to video, mic, and screen share features. For the zero-cost infrastructure, I can compare options like WebRTC and Jitsi, or propose a lightweight self-hosted signaling server if needed. Once the prototype is functional, I'll provide the source code, build instructions, and notes on how we can scale without incurring fees. Let’s get started on creating this reliable proof of concept. Best regards, Billy Bryan

Intrigued by your project's simplicity and emphasis on proof of concept, my goal is not just to deliver working source code with meticulous build instructions but also provide insights into the chosen solution's scalability at no additional cost as per your request. So let's embark on creating a basic yet reliable video call app together!

@abhis1243655

I understand you need a clean one-to-one video call MVP for iPhone, iPad, and Android, built with .NET MAUI—featuring stable two-way video/audio, screen sharing, basic email login, session timeout, and a single user role. For a zero-cost setup, I can evaluate WebRTC (with a custom signaling server using Node or Python) or Jitsi Meet SDK for integration. Both can work without monthly fees, depending on your hosting preference. Once you confirm which option you’d like me to explore first, I can prepare a short plan covering architecture, timelines, and tech stack details.

@vikkaspattel

Hi, I’ve carefully reviewed your project, and as a senior C# developer with experience in .NET Maui, I can deliver this 1-to-1 video and screen-share MVP for you. I'll build the app in .NET Maui as requested, ensuring it runs smoothly on iPhone, iPad, and Android. Infrastructure Approach (Zero-Cost): You are correct to look at WebRTC. For the signaling server (the "zero-cost" part), I would build a lightweight ASP.NET Core WebSocket server. This is much leaner than a full Jitsi instance for 1-to-1 calls, and it keeps your entire tech stack in C#. It can run on a minimal VPS. Core Needs: Auth: I'll use ASP.NET Core Identity for email/password sign-in and manage the session-timeout. This will connect directly to your SQL Server. Media: I will integrate WebRTC for the stable two-way video/audio. Screen Share: I'll implement the native screen-sharing APIs on iOS/Android and pipe that stream into the WebRTC connection. Deliverables & Trade-offs: You'll get the full source code for both the .NET Maui app and the ASP.NET signaling server, with the requested build/tech notes. The trade-off for this "free" (WebRTC) approach is NAT traversal. For the POC, we can use free STUN/TURN servers. For a production app, a paid TURN service (like Twilio) is the main "future cost," but it's minimal and usage-based. I'm Vikas Patel, and I'm ready to build this. Best, Vikas Patel

I have 7+ years of experience delivering straightforward, robust video calling solutions across iOS and Android platforms. ✅ Implement direct WebRTC for peer-to-peer video and audio to enable seamless two-way communication without recurring fees. ✅ Integrate flexible screen sharing toggled by either participant, managing real-time updates for instant visibility. ✅ Develop secure email/password authentication with session-timeout logout to address your idle user concern. ✅ Build with .NET C# Maui for native performance across iPhone, iPad, and Android, compliant with store policies. ✅ Document thoroughly with build instructions, explanation of video stack choices, and hosting trade-offs balancing cost-free scaling versus custom signaling server options. Thanks and Regards. Which free WebRTC signaling options have you already considered, and would you prefer a completely serverless approach if feasible?

@yuriil44

Hi there, I’ve reviewed your project and I can help you develop the MVP for a cross-platform video call app with screen sharing on iPhone, iPad, and Android. I will ensure the app meets your core requirements and delivers a clean, reliable experience. I will implement stable two-way video and audio communication on all three platforms. Either participant will be able to start or stop screen sharing at any time, and the other party will immediately see the shared screen. I’ll also include a simple email/password sign-up/login system with a session-timeout safeguard to log out idle users. The UI will be minimal, with a login screen and a call screen featuring basic controls for video, mic, screen share, and hang up. I will focus on zero-cost infrastructure, using WebRTC, Jitsi, or other free SDKs/APIs. If necessary, I will propose a lightweight self-hosted signaling server using Node, Go, or Python to avoid recurring costs. I’m confident I can deliver a stable prototype quickly, and once the proof of concept is in place, we can discuss future iterations. Thanks, Yurii
