I am building a full-featured social voice platform, not just a calling utility, and I need an experienced Flutter developer who already knows ZEGOCLOUD Basic SDK and ZIM SDK inside out. The project mirrors the polished feel of apps like Infriends or Yalla—my Figma files are ready to guide every pixel—so expect high-end, custom UI work from day one. Core audio-room features must ship complete: • 8- and 12-seat multi-guest rooms • Advanced seat controls: lock / unlock, mute, admin privileges, kick-out and block users • Real-time virtual gifting with lively on-screen animations • PK battle system, room levels and VIP badges that update instantly as users interact A Node.js / Firebase backend will power authentication, user profiles, diamond balances and purchase history. Data flow must stay in perfect sync with the ZEGOCLOUD layer, and every transaction should be ready for future app-store review. I will fund the build through clearly defined milestones that fit within the overall fixed price. The total timeline is 45–60 days, so efficient, test-driven delivery is essential. To confirm your fit, send a short video or live link to any audio-room app you have already shipped with ZEGOCLOUD. Seeing those SDK skills in action will fast-track our conversation and the final selection.

Hello there, I will build your social voice platform in Flutter with ZEGOCLOUD SDK integration for 8 and 12-seat audio rooms, seat controls (lock, mute, kick, admin privileges), real-time virtual gifting with on-screen animations, PK battle system, and room levels with VIP badges, backed by a Node.js and Firebase backend. For the gifting animations, I will render them in a separate overlay layer using Lottie so they play smoothly without interrupting the audio stream or causing frame drops on mid-range devices. Questions: 1) Do you have the ZEGOCLOUD account and SDK keys ready, or do you need help with the initial setup? 2) Should the diamond and currency purchase flow use Google Play and App Store in-app purchases, or a third-party gateway? Send me a message and we can go over the details. Best regards, Kamran

Hi, Building a premium voice room app like Yalla or Infriends requires precise ZEGOCLOUD integration, real-time state sync, and smooth Flutter UI. I can deliver a production-ready app with advanced room controls, gifting, and PK battle features aligned exactly with your Figma designs. Here’s how I’ll approach it: • Flutter app with high-end custom UI and smooth performance across Android and iOS • Full ZEGOCLOUD integration (Basic SDK + ZIM SDK) for multi-seat rooms, seat control, and real-time messaging • Advanced room features: mute, lock/unlock seats, admin controls, kick/block users • Real-time gifting system with animations, diamond balance sync, and purchase tracking • PK battle system, VIP badges, room levels, and live interaction updates • Node.js or Firebase backend for authentication, user profiles, wallet, and transaction management • Clean, modular architecture ready for scaling and App Store compliance I focus on building real-time social apps that remain stable, fast, and scalable even with high user concurrency. Let’s connect on chat. I can review your Figma and begin implementing the ZEGOCLOUD voice room architecture right away.

You’re not building a simple voice chat app this is a polished, multi-seat social audio platform with real-time interaction, gifting dynamics, PK battles, and live role controls similar to Infriends or Yalla. The experience must feel premium from day one, with flawless seat management, instant UI feedback, and smooth performance under high concurrency. The build will cover 8–12 seat audio rooms, advanced host/admin controls (lock, mute, remove, block), real-time virtual gifting with animated reactions, PK battle mechanics, live room levels, VIP badge updates, and synchronized balance/transaction handling. I’m assuming authentication, user profiles, and in-app currency logic must remain perfectly aligned across the entire system. Scope: audio-room core → role & seat management → gifting & PK system → profile & balance sync → admin moderation logic → testing & performance tuning → milestone-based delivery within 45–60 days. For a real-time social platform, interaction latency and sync accuracy must be locked down early architectural alignment should happen immediately before development begins to ensure smooth scaling and store approval readiness.

Your PK battle system will fail under concurrent load if you don't implement optimistic locking on the Firebase diamond transactions. I've seen three voice-chat apps lose thousands in disputed purchases because they skipped transaction rollback logic during network hiccups. Before we architect the seat-management layer, I need clarity on two things: What's your expected peak concurrent room count—are we designing for 50 rooms or 500? And does your diamond purchase flow require PCI compliance, or are you routing through Apple/Google IAP exclusively? Here's the technical approach: - ZEGOCLOUD BASIC + ZIM SDK: Build the 8/12-seat room engine with granular seat states (locked, muted, occupied) using ZIM's custom signaling to sync admin actions across all clients in under 100ms. - FLUTTER CUSTOM UI: Translate your Figma specs into reusable widget trees with AnimatedBuilder for gift animations and StreamBuilder for real-time badge updates—no janky setState calls that kill performance. - NODE.JS + FIREBASE: Design a transactional API layer with Firestore batch writes and Cloud Functions triggers to handle diamond deductions, ensuring atomic operations that survive race conditions during PK battles. - AUDIO PROCESSING: Implement ZEGOCLOUD's noise suppression and echo cancellation presets, then add fallback logic for iOS interruptions (calls, Siri) so rooms don't crash mid-session. - BACKEND SYNC: Use Firebase Realtime Database for live room state (levels, VIP status) and Firestore for purchase history, with webhook validation to prevent client-side spoofing of gift transactions. I've shipped two ZEGOCLOUD-powered apps—one scaled to 12K daily active rooms with zero audio dropouts. I don't take projects where the monetization logic isn't bulletproof. Let's schedule a 20-minute call to walk through your Figma flows and discuss edge cases like what happens when a user gets kicked mid-gift animation.

Dear Employer, We have over 8 years of experience in web and app development. I’ve carefully read your requirement, and this is clearly not just a voice-chat feature — this is a full-scale social audio ecosystem similar in experience quality to Infriends/Yalla, with real-time engagement, gifting economy, and competitive PK dynamics. We already work with Flutter + real-time communication SDKs, including structured seat-based room logic, role permissions, and synchronized backend state management. Your requirement for tight sync between ZEGOCLOUD (Basic + ZIM SDK) and a Node.js/Firebase backend is well understood — especially around diamond balances, purchase validation, and App Store–safe transaction handling. Here’s how we would approach it: • Structured audio room engine (8 & 12 seats) with dynamic seat state sync • Admin controls: lock/unlock, mute, promote, kick, block (real-time ZIM events) Milestones would follow a feature-first release cycle: Auth + profile + wallet system Audio room core + seat management Gifting + animations Timeline of 45–60 days is realistic with disciplined sprint execution. We’ve built real-time multi-user systems before and can share a demo privately that showcases seat control logic and live gifting flow. A couple quick clarifications: – Will gifting animations be Lottie-based or custom-rendered? – Are PK rewards tied to diamonds or ranking tiers? Looking forward to discussing this further.

I’ve built audio-room apps with ZEGOCLOUD and handled complex seat controls like locking, muting, and admin roles. For a client in social voice chat, I delivered smooth multi-guest rooms including real-time gifting and live badge updates, all syncing flawlessly with a Node.js/Firebase backend. One key part is keeping your diamond balances and purchases tightly in sync with ZEGOCLOUD events, and I’d double-check that all transactions are logged cleanly for app store reviews. Have you planned the flow for handling race conditions during simultaneous gifts or seat changes? Also, would you want the PK battles to support live state recovery after network drops? Your Figma files will help nail the custom UI from day one, and my past app shipped all core features within a similar 45-day timeline by focusing on test-driven development and milestone-based delivery. I’m ready to review your Figma and start building your polished social voice chat app immediately.

Hi, As per my understanding: You are building a premium social voice platform with multi-seat audio rooms powered by ZEGOCLOUD (Basic SDK + ZIM), not just simple calling. The app must support 8/12-seat rooms, advanced seat moderation (lock, mute, kick, block, admin), PK battles, live gifting with animations, and real-time VIP/level updates. A Node.js/Firebase backend will manage auth, wallets, diamonds, and transaction history, fully synchronized with the ZEGOCLOUD layer. Timeline: 45–60 days with milestone-based delivery. Implementation approach: I will structure the app using Flutter with clean state management (Bloc/Riverpod) and modular architecture. ZEGOCLOUD audio engine and ZIM signaling will handle room logic, seat states, and PK sync with low latency. Backend APIs (Node.js + Firebase) will securely manage balances, gifting transactions, and role permissions with real-time listeners to prevent desync. Animations will be optimized for performance. I’ll implement transaction validation suitable for future store review. Development will follow milestone sprints with continuous testing and staging builds. A few quick questions: Target launch platform: Android first or simultaneous? Do you require in-app purchases or external payments? Expected peak concurrent users? Do you already have ZEGOCLOUD enterprise plan?
