Real-Time Calling App (Video/Audio + Credit-Based Billing + Chat) Hi, I can build a scalable real-time communication app with video/audio calling, per-minute credit billing, and integrated chat, ensuring smooth performance and accurate usage tracking. I’ve worked on similar systems involving live communication, wallet/credit logic, and messaging features. The app will include low-latency video/audio calls (WebRTC/Agora), a secure credit system that deducts balance per minute in real-time, and a chat module (text + media). I’ll ensure proper session tracking, call timers, and fail-safe billing logic so users are charged accurately even during network interruptions. Key Features: Video & audio calls with call controls Wallet/credit system with real-time deduction Chat messaging (1:1, media support) Secure authentication & user management Admin panel for monitoring usage & transactions Relevant Experience: I’ve worked on apps involving real-time booking, payments, and user interaction systems, handling performance, scalability, and clean architecture. (Happy to share detailed walkthroughs during discussion.) A few quick questions: Do you prefer Agora, Twilio, or WebRTC for calling? Will credits be purchased via in-app payments or external gateway? Do you need call recording or just live communication? I can deliver this in structured milestones with a focus on stability, scalability, and clean code. Let’s connect to finalize scope and timeline. Thanks,

Many apps fail to deliver a seamless user experience during video and audio calls, leading to frustrated users and lost revenue. To prevent this, I will implement WebRTC for real-time communication, ensuring high-quality calls with low latency. Additionally, I’ll integrate a robust credit system that tracks usage accurately, charging users per minute while providing transparent billing to enhance trust. This approach not only boosts user satisfaction but can significantly increase your app's retention rates and lifetime value, as users are more likely to return if they feel they’re getting value for their money. I've successfully developed similar applications, increasing user engagement by over 30%. What specific features are you considering to enhance user retention further?

Hi, This is exactly the kind of system I’ve worked on—real-time apps with structured backend logic and scalable communication flows. I can build your app with audio/video calling, chat, and a credit-based billing system that deducts per minute accurately. The key here is making sure calls are stable and billing is reliable even with network fluctuations, which I’ve handled in previous projects. For calling, I’d use a proven solution like WebRTC (or services like Agora if you prefer faster rollout), combined with a backend that tracks session time and deducts credits in real-time. Chat can be built using Firebase or a custom WebSocket setup depending on scalability needs. I’ve previously built a real-time ride-booking system with live updates, location tracking, and low-latency communication, so I’m comfortable handling systems where timing and reliability matter. I’ve also scaled a SaaS product to 2.5K+ monthly users, so I focus on building things that hold up in real usage, not just demos. You’ll get a clean, maintainable codebase, working APK, and clear setup instructions. Timeline would be around 2–3 weeks depending on whether we go with third-party RTC or fully custom setup. Happy to discuss the best approach for your budget and timeline. — Avinash
