Hi — Elias here from Miami. I see you’re looking to develop a full-stack Flutter multivendor event planning marketplace. The goal seems to be creating a seamless platform for users to connect and manage events effectively. What usually matters most here is scalability. As the user base grows, ensuring the app can handle increased traffic and interactions is critical. A common issue in systems like this is maintaining smooth workflows while managing diverse user roles, from vendors to event planners. My approach would focus on structuring the app with robust backend APIs to support future growth and integrations. I’d prioritize a clean architecture that facilitates maintainability and allows for quick iterations. Drawing from my experience with similar platforms, I’ve tackled challenges like user permissions and data management, ensuring systems can adapt as needs evolve. A few questions to better understand the scope: Q1 – What specific user roles do you envision, and how will their permissions vary? Q2 – Are there any third-party integrations you're considering for payments or notifications? Q3 – What are your scaling expectations for the user base in the first year? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hello there I am interested in your project and can present my previous work as references. I can build the complete Flutter marketplace for iOS and Android with a scalable backend, database, REST APIs, and responsive admin panel. I would use Flutter with a structured architecture, Node.js with PostgreSQL for the backend, and Firebase Cloud Messaging for notifications. All critical rules such as vendor matching, service radius, memberships, coin deductions, bidding eligibility, payments, roles, and subscriptions would remain server side for security and consistency. The main challenges are the 60 plus screen client and vendor workflows, accurate location based vendor matching, and reliable wallet, bidding, subscription, and payment logic. I would handle these through clear API contracts, modular backend services, proper database design, automated testing, and milestone based delivery with each stage fully tested before approval. Portfolio: https://www.freelancer.com/u/Hammadhassan21 Could you share your preferred payment gateway and whether the UI designs for the 60 plus screens are already available so I can prepare the milestone plan, timeline, and cost accurately? Best regards, Hammad Hassan

The risk here isn't the 60+ Flutter screens — it's keeping matching, coin deductions and bid eligibility strictly server-side so they can't be gamed from the client. I've built exactly this shape of system: Flutter/Kotlin/Swift apps backed by Node.js + PostgreSQL (PostGIS for radius/geo queries) with Redis, plus admin dashboards with RBAC, and multi-provider payment gateways handling subscription billing and commission tracking with an auditable transaction ledger. Approach: (1) lock the data model, API contract and matching/coin rules as a written spec; (2) build vertical slices — auth/roles, event request → matching → bidding → wallet, then chat/notifications — each shipped to TestFlight and Play internal track for your sign-off; (3) admin panel, payments, analytics, launch and post-launch support. Which payment provider and region should the coin purchases and memberships target?

@joomextensions

Hi, stack: Flutter (Riverpod, clean architecture) for client and vendor apps, Laravel REST API with PostgreSQL + PostGIS for radius matching, React admin panel, FCM, Stripe subscriptions and coin purchases, Pusher for chat. All rules stay server-side: vendor matching by service, availability and radius, membership permissions, coin deduction and bid eligibility via policies and DB transactions. Custom premium UI in Figma for 60+ screens incl. empty/loading/error states. Milestones: 1 design + architecture, 2 auth, profiles, events, matching, 3 bidding, wallet, memberships, payments, 4 chat, reviews, notifications, 5 admin, analytics, QA and store launch. Pay only on approved milestones is fine. 3 months free support. Regards, Harsh Thoriya

@Hubready

Hello!, I am a US-based senior software engineer and I’d love to help build your Flutter multivendor event marketplace. The real challenge here is not just building screens, but making the organizer, vendor, attendee, booking, payout, and admin flows work together cleanly without creating a system that becomes hard to maintain later. My approach would be: 1. Define the marketplace logic first: roles, bookings, approvals, cancellations, notifications 2. Build the Flutter app with a clean, easy booking experience 3. Set up the backend, database, and APIs correctly from day one 4. Test the full flow end to end so the platform is stable at launch I build with both the business side and the technical side in mind, and I pay close attention to the small details that usually decide whether a marketplace feels polished or frustrating. Relevant work includes a local service booking app, a vendor marketplace dashboard, an event RSVP platform, and a Flutter-based delivery management app. Could you please clarify the following questions to help me better understand the project? 1. Do you want split payouts or escrow for vendors? 2. Should vendors create listings directly, or go through admin approval? 3. Do you already have UI mockups, or should I help define the user flow? If you want this done carefully and built to scale, I’d be glad to discuss the best path forward. James Zappi

Hi there, I have read the details and can develop your complete Flutter-based multivendor event planning marketplace for iOS & Android, including the backend/API, database, and responsive admin panel. I have already developed similar marketplace platforms with vendor management, bookings/requests, bidding, wallets, subscriptions, payments, location-based matching, chat, notifications, and admin controls. Development approach: • Design and structure the 60+ Flutter screens with client/vendor journeys and all required states • Build a scalable backend with secure REST APIs, RBAC, business rules and database architecture • Implement vendor profiles, availability, service-radius matching, event requests and bidding • Add memberships, coin wallet, payments, subscriptions and transaction management • Integrate maps/location services, chat, push/email notifications, reviews and verification • Develop the admin panel for users, vendors, events, categories, memberships, coins, payments and reports Suggested Stack: Flutter, Node.js/NestJS or Laravel, PostgreSQL/MySQL, Firebase, Google Maps, and a suitable payment gateway. I can provide clean API documentation, milestone-based development and post-launch support. Questions: Do you already have the UI/UX designs, or should our team handle the complete 60+ screen design? Which countries/currencies and payment/subscription providers should the platform initially support? Thanks Rahul

@AITSoft

Hi, I understand you need a complete Flutter event marketplace for iOS and Android, with separate vendor and client journeys, backend APIs, database, payments, subscriptions, coin bidding, matching by location, chat, notifications, and a responsive admin panel. I would first plan the database and API structure around the main business rules, keeping matching, service radius, membership access, coin deductions, bid limits, roles, payments, and security on the server. Then I would build the mobile apps and admin panel in clear milestones, covering the 60+ screens along with loading, empty, error, and confirmation states. Dart and Flutter will help keep the mobile code clean and consistent, while properly documented API endpoints will make the system easier to maintain and expand. I can also cover map and radius logic, vendor availability, wallet transactions, subscriptions, messaging, push notifications, reviews, testing, deployment, and post-launch fixes. Each milestone can have fixed deliverables and testing before approval, so progress stays clear and verifiable. I can share relevant Flutter, Android, API, marketplace, payment, and admin work examples with the proposed stack, architecture, timeline, and milestone plan. Which payment, map, email, and push-notification providers do you want to use, and should vendor matching run instantly or through scheduled jobs? I am interested in building this as a stable long-term platform rather than only delivering screens. Please

@melikatfz

A multivendor marketplace with sixty plus screens and server side bidding logic requires strict state management and a normalized relational database to keep queries fast. Handling geolocation radius checks alongside coin deductions on the backend prevents race conditions when multiple vendors bid simultaneously. Node with PostgreSQL or Laravel combined with Flutter works well here, as both handle complex transactional logic cleanly without overhead. How are you planning to structure the initial vendor onboarding and verification workflow before they gain bidding access?

@zainalitariq245

Hey there, You need a complete Flutter marketplace where vendor matching, radius based eligibility, bidding, memberships and coin deductions are enforced on the backend, not trusted to the mobile apps. The 60 plus screen client and vendor journeys also need consistent loading, empty and error states. I can approach this as a full stack build with Flutter for iOS and Android, a structured API and database, plus a separate responsive admin panel. I would keep business rules server side, with clear roles, API authorization, transaction safe wallet handling, documented APIs and an architecture that can grow as vendors and events increase. One question, do you already have a preferred backend and hosting environment, or would you like the development partner to recommend the full stack and deployment architecture? Looking forward to working together. My portfolio and client reviews, https://www.freelancer.com/u/zainalitariq245 Best regards, Zain Tariq.
