                         About Drago Live 
Drago Live is a live streaming + virtual gifting + gaming app (think Bigo/Poppo/Tango vibes) built with Flutter & Dart.
We use ZEGOCLOUD UI Kit & SDK for live video, beauty filters, PK battles, audio rooms, and more.
We’re scaling fast and need a senior engineer who knows ZEGOCLOUD inside out.
Role 
Own the end-to-end integration and optimization of ZEGOCLOUD features in our Flutter app across Android and iOS—from beauty filters to PK battles and moderation controls—while keeping performance silky smooth and battery-friendly.
What you’ll build 
•	Live Streaming: host/guest flows, co-hosting, PK battles, multi-guest, invite/signaling.
•	Beauty/Effects: beauty filters, stickers/overlays, effect intensity controls, device-adaptive quality.
•	Realtime Comms: 1:1 & group video/voice calls, audio rooms, spatial audio (if supported).
•	Chat & Signaling: room chat, reactions, gifts, robust reconnect & state sync.
•	Room Management: create/join/end, seat management, permissions, host tools.
•	Moderation: mute/kick/ban, content safeguards, report flows, admin dashboards hooks.
•	Virtual Gifting: gift animations, lucky gifts, combos, gift-led events & counters.
•	Performance: fps/bitrate tuning, thermal & energy optimization on iOS, crash-free stability.
•	Platform Plumbing: push notifications, deep links/universal links, background modes (nice to have).
Must-have skills 
•	3+ shipped Flutter apps with substantial ZEGOCLOUD UI Kit/SDK integration.
•	Strong grasp of ZegoExpressEngine concepts: rooms, streams, tokens, signaling.
•	Implemented beauty filters, PK battles, audio rooms, stickers, and virtual gifting in production.
•	Proven performance tuning: bitrate ladders, CPU/GPU tradeoffs, device gating, thermal handling (iOS).
•	Solid iOS & Android platform chops: entitlements, background modes, permissions, ProGuard/obfuscation.
•	CI/CD familiarity for Flutter (fastlane, code signing, Play/App Store basics).
Nice to have 
•	Experience with Parse Server or similar BaaS, Firebase Messaging, Dynamic/Universal Links.
•	Anti-abuse/mod tooling (rate limits, moderation queues).
•	Analytics & A/B testing for engagement features.
Hardware / Work setup 
•	MacBook required (for iOS builds/signing).
•	iPhone preferred for on-device testing (Android device also preferred).
•	Remote OK; strong async communication and fast iteration expected.
Success looks like 
•	< 2s stream start time on good networks.
•	< 300ms end-to-end latency for interactive features (where feasible).
•	<1% crash rate; no iOS thermal throttling under common presets.
•	Smooth PK/beauty/gifting at scale with clean room state and zero “ghost” sessions.
Engagement 
Freelance/contract (with option to extend).
Start ASAP.
