Your real-time video infrastructure will bottleneck under concurrent load if WebSocket connections aren't pooled correctly and TRTC room lifecycle isn't managed at the API layer. This causes dropped calls and memory leaks that kill user retention. Quick questions - are you currently handling TRTC token refresh server-side with Redis caching? And is your PostgreSQL schema normalized for the agency commission calculations, or are you recalculating on every withdrawal request? Here is the architectural approach: - FLUTTER + RIVERPOD: Refactor state management to isolate WebSocket listeners from UI rebuilds, preventing frame drops during live streams and reducing battery drain by 40%. - FASTAPI + SQLALCHEMY: Optimize your wallet transaction queries with proper indexing and implement idempotent payment webhooks so Stripe/Razorpay retries don't create duplicate credits. - DOCKER + AWS: Set up horizontal pod autoscaling for your FastAPI containers and configure Nginx load balancing to handle 10K+ simultaneous video sessions without degrading latency. I've built 3 production video platforms (2 dating apps, 1 live streaming SaaS) that scaled past 100K users with sub-200ms API response times. Let's schedule a 20-minute technical call to review your current architecture before you commit to the next development phase.

LunaConnect isn't at the stage where another developer should start rebuilding pieces—it's at the stage where every change has to respect an existing architecture while moving features forward without breaking real-time flows. With a Flutter app, FastAPI backend, admin panel, wallet, authentication, live streaming foundation, messaging, and documentation already in place, the priority is continuity, not reinvention. My first step would be reviewing the current codebase and documentation to understand existing patterns, identify architectural bottlenecks, and map pending work before introducing new features. From there, I'd focus on improving Riverpod state management where needed, optimizing FastAPI services, reviewing WebSocket and RTC integrations, validating PostgreSQL/Redis interactions, and extending modules like wallets, memberships, live interactions, and admin features while keeping releases stable. Performance profiling, bug fixes, and incremental architectural improvements would happen alongside feature delivery rather than through disruptive refactors. I've worked on production applications involving Flutter, FastAPI, real-time communication, payment workflows, Docker-based deployments, and API-driven architectures, so I'm comfortable stepping into an active project instead of expecting a fresh start.

Your project requires maintaining and extending a production-grade platform, and my focus is on reviewing existing architecture, improving code quality, and delivering new features without compromising scalability or performance. My approach is to analyze the current codebase before implementation, optimize APIs and database interactions, strengthen real-time communication workflows, enhance payment integrations, and ensure clean, maintainable architecture across the mobile app, backend, and admin panel. I'd be glad to discuss your existing architecture and the most effective roadmap for the next development phase. Best regards

@shayankhan333

Joining a codebase with thousands of hours already invested is a different challenge than greenfield work. The first priority is understanding the existing architecture decisions before changing anything. I've built real-time communication apps with Flutter and FastAPI, including video calling with WebRTC-based SDKs, wallet systems with dual-currency logic, and WebSocket-driven chat. For LunaConnect, I'll start with a thorough code review of the Flutter app and FastAPI backend, then move into bug fixes and feature completion based on your priority list. I'm comfortable with Riverpod, clean architecture, and the full DevOps setup you've described. One thing worth flagging early: Tencent TRTC's Flutter SDK has some rough edges around room reconnection handling and participant state sync. Best regards, Shayan

With over a decade of experience in Full-stack Development, I'd present myself as the ideal candidate for your Flutter + FastAPI project. I have a profound understanding of clean, maintainable code, scalable architectures, and stringent coding standards required to deliver high-quality projects with utmost precision. My previous projects align surprisingly well with your vision, for instance, my proficiency in creating social media apps and large-scale APIs can be leveraged to create LunaConnect—an app designated to connect people like yours. I proactively indulge in peer code reviews before initiating any change to existing codes. Consider that as an added security since I can provide well-thought-out solutions when necessary rather than blindly following instructions. In addition to this, my extensive background in Flask and Python-based FastAPI matches remarkably well with your requirements. The experience doesn't stop there! I'm acquainted with working on video call apps, live streaming apps, real-time chat applications as well as payment gateways; all of which are integral components to making LunaConnect stand tall among its contemporaries. Lastly and most importantly, as you've already invested thousands of hours into this project from which I could make the best out, I'm available 'round the clock contributing readily without delay (time-zone flexibility).

@Appworldz

Hi! LunaConnect is exactly the kind of complex product I enjoy working on. I have 8+ years in Python/FastAPI and 5+ years in Flutter, building real-time apps with WebRTC/TRTC, wallets, subscriptions, live streaming, Docker, AWS, Redis, and scalable APIs. I always review the existing architecture before writing a line of code and suggest improvements where they matter. I'm available 35–40 hrs/week (AEST/IST overlap). Rate: ₹3,500/hour (or milestones after code review). The posted budget is suitable for an initial phase, not the full long-term scope.

@jagratip3

Hi, I can take over and continue LunaConnect from the existing codebase rather than rebuilding what is already working. I understand this is a complex production platform where Flutter, FastAPI, real-time communication, wallets, payments, streaming, messaging, and admin workflows all need to remain consistent as new features are added. I’ll begin with a structured codebase and architecture review across Flutter/Riverpod, FastAPI/SQLAlchemy, PostgreSQL, Redis, WebSockets, Docker, and the existing integrations. From there I’ll identify technical debt, bugs, performance bottlenecks, and areas that need stabilization before extending functionality. On the mobile side, I can work with Clean Architecture, Riverpod, GoRouter, Dio, animations, REST APIs, real-time states, and complex user flows. On the backend, I can work with FastAPI, authentication, WebSockets, database optimization, Redis, background processing, payment/wallet logic, and scalable API design. I’m also comfortable working with Docker/AWS-based environments and integrating third-party services where required. For RTC/streaming functionality, I’ll focus on reliable session handling, connection states, permissions, lifecycle management, and graceful failure/reconnection. I’m available for long-term collaboration and can start by reviewing the documentation and current repository to establish the first development milestones. Best, JP
