With over 6 years of experience in mobile and web app development, I bring a proven track record of not just building apps, but ensuring they are approved and successfully deployed. My core skills in Flutter and React Native, Firebase, Stripe for payment integration, and GoRouter for navigation align perfectly with your project's needs. And my previous experience will be particularly useful for this project as I've built and shipped apps that deal with real-time video streaming and in-app payments — two key components your platform is built upon. One of my specialties is clean app architecture which allows for gradual, modular expansion -- exactly what you need for your long-term engagement. In line with your requirement, I will provide a detailed estimate of the hours needed for each module based on thorough analysis of its complexity and dependencies. In fact, I believe in continuous testing to ensure flawless performance even during large-scale updates -- and cherish clients who appreciate such methodologies.

Hi, I am a full-stack Flutter and Node.js developer with 8 years of experience extending live production platforms, real-time features, payment flows, MongoDB systems, and mobile applications with clean architecture. I understand this is an existing product with completed designs, so I would first review the repository and work module by module without disturbing the current production features. For the listed scope, my preliminary estimate is approximately 550–750 hours. This includes the economics rules layer, creator wallets and payouts, communities, currency, battle formats, advertising, localisation, dark theme, real-time integrations, iOS camera effects, testing, and store submission. I would confirm the estimate after the NDA and technical review. I work as an individual senior developer, so there is no agency team or separate role markup. My proposed rate is $6/hour. I will maintain the shared task and hours sheet and provide a written weekly report. Testing will include unit, API, socket, integration, device, payment, and regression testing. I will correct defects caused by my implementation without additional charges. I'm an individual freelancer and can work in any time zone you prefer. Please contact me with the best time for a quick chat. Thanks, Emile

Hi, Ankit here. I understand you need a Flutter and Node.js team to extend a live streaming social platform across backend, admin panel, and mobile, adding a configurable rules layer with versioning, a creator wallet with multiple balances and payouts, group communities, a second currency, new battle formats, an ads module, localisation, dark theme, iOS camera effects, and store submission. What usually matters most here is the configurable rules layer, since platform economics drive payouts, currency, and battle scoring, and versioning with effective dates means every historic transaction has to resolve against the rules live when it happened. A common issue in live platforms adding money modules is that new balances get bolted onto the existing wallet without migration, so old and new transactions read different rules and the ledger stops reconciling. The tricky part is the creator wallet, since multiple balances and money states interact with payouts, the second currency, and the rules layer. My approach would be to start with the rules layer and wallet model as one design, then build modules in your priority order with clear interfaces between backend, admin, and mobile, plus shared task tracking and weekly reports. Looking forward to hearing from you.

Hi, I've worked with full-stack applications involving Flutter, Node.js backends, real-time communication, and API-driven features, so extending an existing production platform like this requires careful understanding of the current architecture before adding new modules. I understand the priority here is maintaining stability while expanding complex social and streaming features. Could you share the current repository structure and which modules are highest priority for the first development phase? I would start by reviewing the existing backend models, socket architecture, Flutter clean architecture, and deployment flow. From there, I would estimate each module separately, implement changes in isolated stages, and keep strong testing around real-time events, payments, and user flows to avoid regressions. I can work with your existing design system and focus only on development and delivery. Happy to review the platform details after NDA and discuss the first milestone. Best regards, Abdul Mannan

Hello, Ryan here from San Francisco. My guess is the hardest part of this isn't the module list itself but the rules layer underneath it: a versioned economics engine that the wallet, the second currency, and the new battle formats all have to read from without conflicting balance states during live socket events. That's the piece I'd want to get right first, because a wallet payout workflow built before the rules layer is stable usually needs rework once real money states hit edge cases like mid-battle disconnects or refunds. The other open question is your streaming layer. The post lists LiveKit or Agora as either/or, which tells me the choice may not be locked yet, or it's already running on one and I should just extend it rather than assume. Knowing which is live changes how I'd scope the new battle formats and iOS camera effects, since the SDK dictates what's feasible on the client side without a rewrite of the existing socket handling. Given the 355 endpoints and 5,800-line socket layer already in production, I'd start by reading the current data models around balances and battles before touching anything, so the new group communities and advertising module slot in without breaking existing flows. If you can confirm which streaming SDK is actually deployed, I can speak more precisely to the mobile-side effort. Best, Ryan

Enhancing your live-streaming social platform aligns perfectly with my expertise. Given the complexity of the existing architecture, I estimate around 300 hours for the new modules, including the rules layer and wallet integration. This figure considers the need for a deep understanding of your current system and the implementation of multiple features. I propose a team of two: a Node.js developer at $5 per hour and a Flutter developer at $5 per hour. Both have experience in real-time applications and payment integrations. I’ve successfully delivered similar projects, including a video chat app and an e-commerce platform with in-app payments. Testing is crucial; I ensure thorough unit testing, and any defects found in my work will be corrected at no additional cost. What specific features are you prioritizing for the initial module roll-out? I look forward to collaborating on this exciting project. Regards, EnriqueHR

Hello, I understand you are looking to enhance your existing live-stream social platform using Flutter and Node.js. This requires a collaborative approach to build new modules while ensuring seamless integration with your current architecture. To start, I propose a high-level approach where we initiate with a detailed scope refinement session to prioritize modules and clarify any uncertainties. This will help in estimating the total hours accurately. A few questions to consider: What specific functionalities do you envision for the creator wallet and the advertising module? How do you foresee versioning and effective dates impacting the rules layer? Studio SJ operates on paid fixed-price, milestone, or hourly engagements. Is this acceptable for your project? Looking forward to discussing this further. Sone Joubert Studio SJ

How are the modules prioritised? That will help me give a tighter hours estimate against the existing backend and Flutter structure. I estimate around 1,500–1,800 hours for the full scope, including backend, Flutter, admin, payments, wallet, real-time features, localisation, testing and store submission. Team: Flutter $5/hr, Node.js $5/hr, QA $3/hr. I can provide the actual developers’ CVs and two live application links. Our own implementation defects are fixed at no extra cost. I can start immediately. Regards Rana.R
