TuneQueue is currently a working prototype built in Replit for managing song requests and DJ queues at a single venue. I need an experienced developer to take the existing TuneQueue codebase and turn it into a real, scalable commercial product. The main problem The current version is essentially designed around one venue. The architecture needs to be changed so TuneQueue can support many independent venues simultaneously. Each venue needs its own: Account/workspace Users and staff DJ/queue Spotify connection Settings Customers/song requests Subscription/billing status Data Data must be completely isolated between venues. SaaS / subscriptions TuneQueue needs to become a subscription-based SaaS product. I need: Subscription plans Monthly/yearly billing Online payment Automatic subscription status Trial period if appropriate Upgrade/downgrade Cancellation Payment failure handling Access restrictions when a subscription expires Customer billing management The architecture should make it possible to introduce different pricing tiers later. Scalability The application needs to be designed so that going from: 1 venue → 10 venues → 100 venues → 1,000+ venues doesn't require rebuilding the application. I need the developer to review the current architecture and identify anything that would prevent this from scaling, particularly: Database architecture Authentication Tenant isolation API architecture Spotify OAuth/token storage Backend state Concurrent queue usage Real-time updates Caching Hosting/deployment Background jobs where necessary The existing prototype currently has application state stored in memory, which is not suitable for a multi-venue production system. This needs to be replaced with proper persistent infrastructure. Spotify Spotify integration is a core part of TuneQueue. Each venue should be able to connect its own Spotify account securely. Spotify authentication/token storage therefore needs to be designed around multiple independent venues, rather than one global Spotify connection. Mobile application / App Store The final product needs to become a real mobile application distributed through the Apple App Store and Google Play Store. I don't necessarily want the existing application completely rewritten. The developer should determine the best approach for turning the existing frontend/backend into a mobile product, potentially using a technology such as React Native/Expo or another appropriate solution. The mobile app should use the same production backend/API and support the TuneQueue functionality required by users and DJs. I need: Android app iOS app App Store submission preparation Google Play submission preparation Production builds App icons/splash screens/basic store requirements Secure authentication Connection to the production TuneQueue backend What I want from the developer I already have a working prototype and don't want to start from zero. The job is to: Audit → Refactor → Productionize → Scale → Monetize → Mobile I want the developer to reuse as much of the existing code as makes sense while replacing prototype-level architecture where necessary. The end result should be a commercially viable TuneQueue platform where multiple venues can independently sign up, subscribe, connect Spotify, manage their queues, and use TuneQueue through web and mobile apps. Priority: Get the existing prototype out of Replit and establish the production architecture as quickly as possible, while making sure the architecture doesn't need to be rebuilt again when the number of venues grows.

Hi — Elias here from Miami. I understand this is not a rebuild-from-scratch job. TuneQueue already works; the real task is to remove the single-venue assumptions, replace in-memory state, and turn the prototype into a production multi-tenant SaaS that can scale cleanly. What usually matters most here is tenant isolation and state ownership. I’d audit the current Replit codebase first, then refactor around venue/workspace IDs, persistent database state, per-venue Spotify OAuth tokens, real-time queue updates, background jobs, subscription status, and server-side access controls. For SaaS, I’d structure billing with Stripe subscriptions, trials, upgrades/downgrades, failed-payment handling, and tier-ready entitlements. For mobile, I’d reuse the production API and likely build with React Native/Expo unless the existing frontend suggests a better path. I’ve worked on multi-tenant SaaS, subscription billing, OAuth integrations, real-time systems, mobile apps, and production migrations from prototype architectures. A few questions to better understand the scope: Q1 – What stack is the current Replit app using? Q2 – Which database, if any, is already connected? Q3 – Does the current Spotify flow use one shared account or venue-specific auth already? I’d approach this as Audit → Production Architecture → Multi-tenancy → Billing → Mobile → Launch. Looking forward to hearing from you.

Hello!, This is James from Hollywood... TuneQueue already works as a prototype, so the real job is turning it into a stable, polished platform that handles live song requests, DJ queues, and payments without glitches. That’s exactly the kind of product build I like. My plan would be: 1. Review the Replit prototype and separate what stays vs. what needs rebuilding 2. Tighten the backend for requests, queue logic, admin controls, and MySQL structure 3. Build a clean, mobile-friendly frontend for users and DJs 4. Add secure payment/API integration 5. Deploy, test edge cases, and optimize for speed and reliability I pay attention to the small stuff because with a queue system, the experience lives or dies on speed, clarity, and stability. I’d treat this like a real launch, not just a coding task. Relevant work I’ve handled: - A live booking SaaS for local event vendors - A music/event request dashboard with admin controls - A subscription platform with Stripe flows - A mobile-friendly queue system for hospitality Quick questions: 1. Should users be able to request songs freely, or only after DJ approval? 2. What payment flow do you want first: credits, tips, or subscriptions? 3. Do you want this optimized for web only, or should I structure it with future mobile app support in mind? If you want someone who will care about the details and ship it properly, I’d be glad to help.

Hi I can help transform TuneQueue from a single-venue prototype into a scalable multi-tenant SaaS platform while preserving the valuable parts of the existing Replit codebase. I understand the required approach is Audit → Refactor → Productionize → Scale → Monetize → Mobile. I can review the current architecture, identify scalability limitations, and redesign the foundation for multiple independent venues with isolated data, users, settings, Spotify connections, queues, and subscriptions. I have experience building SaaS platforms, API-driven applications, authentication systems, payment integrations, database architecture, real-time features, and mobile applications. I can help implement proper persistent infrastructure, multi-tenant database design, Spotify OAuth/token management, subscription billing, and production deployment. For mobile, I can evaluate the existing frontend and recommend the best path, such as React Native/Expo, while connecting it to the same production backend for iOS and Android releases. My focus will be on avoiding unnecessary rewrites while replacing prototype-level components that would prevent future growth to hundreds or thousands of venues. I would like to review the current Replit project, technology stack, database structure, and deployment setup to define the migration roadmap and timeline. Best, Justin

Hi, TuneQueue is exactly the kind of prototype-to-production project I work on. I would preserve the useful Replit code rather than rewrite blindly, but replace the architectural pieces that cannot safely support multiple venues. My first step would be an audit of the current frontend, backend, database/state handling, authentication and Spotify integration. I’d then move in-memory state to persistent infrastructure and introduce tenant-aware data models so every venue has isolated users, queues, requests, settings, Spotify credentials and billing state. For production I’d structure the API and database around tenant IDs with enforced authorization, secure encrypted Spotify OAuth token storage, real-time queue updates, background jobs where needed, and subscription lifecycle handling including trials, upgrades, cancellations and failed payments. I’d also keep the backend API independent from the frontend so the same production services can support the web product and subsequent React Native/Expo mobile apps without rebuilding the core. The priority would be getting TuneQueue safely out of Replit and establishing the correct SaaS foundation first.

For TuneQueue, I’d preserve the working prototype where practical but move venue identity, queue state, Spotify credentials, billing, and permissions into a true multi-tenant production architecture before adding mobile distribution. I’d structure the backend around tenant-scoped PostgreSQL data, role-based auth, Redis for active queue/cache state, WebSockets for real-time DJ/customer updates, and background jobs for subscription events, Spotify token refresh, and notifications. My two priorities would be scalability and maintainability: every request should resolve against a venue workspace, and no critical state should remain in memory. That means moving from 10 to 1,000+ venues without redesigning the core system. For billing, Stripe can handle trials, monthly/yearly plans, upgrades, cancellations, failed-payment recovery, and customer self-service while keeping pricing tiers extensible. React Native with Expo is a practical mobile path if the existing frontend can share logic cleanly with the production API. A relevant example is eSimFox, a multi-tenant marketplace built with role-based access, secure payments, real-time events, admin tooling, and architecture designed to onboard new operators and regions without rebuilding the platform.

Hi - Truong here >>>>>>>>>> "MULTI-VENUE SAAS PLATFORM" — you need to turn a working prototype into a scalable product. I’d start with an architecture audit, then replace prototype limitations like memory-based state with proper database structure, tenant separation, and production APIs. The key decision is making each venue fully isolated while keeping the system ready for growth. The main risks are usually authentication, subscription states, Spotify tokens, and real-time queue handling, so I’d address those before adding more features. Is the current Replit project built with a specific backend framework and database, or should I first evaluate the existing stack? Looking forward to working with you.

TuneQueue needs true multi-tenant SaaS architecture, isolated data per venue, and a subscription-ready backend. I’ll audit the existing Replit prototype, then refactor core components to support 1→1,000+ venues without rebuild: tenant-scoped auth/workspaces, database schema with strict isolation, resilient backend state (no in-memory queues), and API + real-time updates designed for concurrent DJ queue usage. I’ll redesign Spotify OAuth/token storage so each venue manages its own secure credentials, then add subscription plans (monthly/yearly), trials, upgrade/downgrade, cancellation, payment-failure handling, and access restrictions when expired, keeping pricing tiers extensible. Finally, I’ll productionize hosting/deployment with background jobs where needed, caching strategy for scale, and create an approach to ship the Android/iOS apps via React Native/Expo (or best-fit alternative) connecting to the same production API, including App Store/Google Play submission readiness and secure authentication.

Hello, "Multi‑Tenant Backend + Shared API For Web And Mobile" - you need TuneQueue moved out of Replit into a clean SaaS architecture that can grow without rewrites. The safest path is to treat each venue as a tenant: separate accounts, queues, Spotify tokens and billing, all mapped in a proper database schema instead of in‑memory state. I’d refactor the current code into a backend (Node.js/FastAPI) with tenant‑aware auth, Spotify OAuth/token storage, and queue state persisted in a database, then expose a stable API that both the web UI and a React Native/Expo mobile app can use. This keeps web and mobile aligned while de‑risking future growth from 1 to 1,000+ venues. I’ve handled similar productionization work before on B2B SaaS‑style platforms, where the priority was getting from prototype to stable multi‑user architecture without throwing everything away: https://www.freelancer.com/u/kasjanovaEste. One edge case is concurrent queue usage: DJs and customers hitting the same venue must see consistent updates. I’d design queue operations as atomic API calls with clear state transitions and background jobs where needed. Which part do you want audited first — the current data model or the Spotify integration? Looking forward to working with you. Fernando

Hi, TuneQueue is already working as a prototype, and the real task is to turn that single-venue setup into a multi-tenant SaaS that can scale safely. I’ve worked on productionizing prototypes by replacing in-memory state with persistent services, tightening tenant isolation, and preparing apps for real billing and mobile deployment. For this kind of build, I’d focus on the database structure, authentication, Spotify token storage, subscription logic, and the backend/API boundaries first. My approach would be to audit the current codebase, identify what can be reused, then refactor the architecture around isolated venue workspaces, subscription enforcement, and production-ready hosting. After that, I’d prepare the mobile path with the same backend so web, iOS, and Android stay aligned. If you want, I can help map the fastest route from Replit prototype to a scalable commercial product. Best regards, Gabriel

Hello, "Multi‑Tenant Backend + Spotify Flow + Mobile Build Plan" – you need to turn a single‑venue prototype into a real SaaS that scales cleanly. I’ll audit the current Replit codebase and map what can be reused, then design a proper multi‑tenant backend (FastAPI or Node.js) with isolated venue accounts, users, queues, Spotify tokens, billing status and persistent storage. Subscription plans, monthly/yearly billing, trials, upgrades and access‑restriction logic can run through Stripe. For mobile, I’ll keep one production API and build Android/iOS in React Native or Expo so DJs and customers use the same backend. I’ve handled similar multi‑user flows and production setups, including mobile + backend work: https://www.freelancer.com/projects/app-store-optimization/ASO-Boost-Downloads/reviews I’ll replace in‑memory state with proper DB models, add real‑time updates where needed, and outline the hosting/deployment path so scaling from 1 to 1,000 venues doesn’t require a rebuild. For Spotify: do you want each venue’s connection stored with short‑lived tokens refreshed automatically, or should I implement a long‑lived refresh‑token cycle with per‑tenant isolation?
