I need a complete cross-platform mobile application (native iOS and Android) that works much like the Freelancer app but targets a different industry niche. Users must be able to create an account with Facebook, Twitter or simply with email, and then post a job by adding photos, videos and documents. Registered agents will browse those jobs and place bids or fixed prices. Core workflow • Job posting with media attachments and category tags • Real-time bidding, offer acceptance and automatic milestone creation • Secure milestone payment flow, dispute centre and resolution dashboard • In-app chat supporting text, voice messages and file sharing (emojis can wait for a later phase) • Push / email notifications for every critical event • Ratings, reviews and basic profile management for both parties I also need an intuitive web-based admin panel so I can verify users, manage disputes and adjust fees. Deliverables 1. Native iOS and Android builds ready for App Store / Play Store submission 2. Source code with clean architecture, API documentation and a Postman collection 3. Admin panel (web) plus database schema 4. Short hand-off guide and two weeks of post-launch bug support Please rely on proven stacks—Swift or Kotlin/SwiftUI for the clients, Firebase or a similar real-time backend is fine as long as payments (Stripe Connect preferred) and media storage remain secure and scalable. Let me know your suggested tech stack, timeline and any relevant marketplace apps you have shipped. P.S. I need the freelancer to put some initiative and input in with some ideas along with some content

Hey, I will deliver your marketplace app — native iOS and Android builds, real-time bidding engine, milestone payment system with Stripe Connect, in-app chat with voice and file sharing, and a web admin panel for user verification, disputes, and fee management. For architecture, I will structure the backend around an event-driven model where each bid, milestone transition, and payment triggers a server-side event that fans out to push notifications, email, and real-time UI updates simultaneously. This keeps every participant in sync without polling and makes adding future event types — like the emoji reactions you mentioned deferring — a single listener addition rather than a refactor. Questions: 1) What industry niche is this targeting? Send me a message and we can go over the details. Best regards, Kamran

Hi, I can build a scalable two sided marketplace app similar in flow to Freelancer with job posting, real time bidding, milestone payments, and a secure chat system designed for production use across iOS and Android. I will develop native mobile apps using Swift for iOS and Kotlin for Android with a shared backend architecture that supports real time job feeds, bidding updates, secure user authentication via email and social login, and media handling for photos videos and documents. The backend will be built using a scalable real time system like Firebase or a custom Node.js layer depending on final load requirements, integrated with Stripe Connect for secure milestone payments, automated escrow handling, and controlled release flows between clients and agents. The platform will also include in app chat with messaging voice notes and file sharing, push and email notifications for all key actions, plus a ratings and review system for both sides to build trust and accountability. I have one quick thing to ask before we start do you want the bidding system to support both live auction style bidding and fixed price offers from the beginning or introduce them in phases? Please check out my profile to review my past projects and portfolio. https://www.freelancer.com/u/Hammadhassan21 I can start immediately and also suggest improvements during development to make the platform stronger and more competitive. Ping me on chat to discuss all the details and move forward. Thanks.

Hi, This aligns well with my experience building AI-driven, data-backed applications. Approach:- Data sourcing: I’d use USDA FoodData Central as the primary structured dataset, with Open Food Facts as a fallback for variety. Data will be normalized into a nutrient-indexed schema for fast querying. Personalisation logic: Start with rule-based macro/micro matching + constraint solver (allergies, preferences), then layer ML (TensorFlow / PyTorch) for adaptive recommendations using user feedback loops (reinforcement signals like swaps/locks). Performance: Precomputed nutrient vectors + caching ensures <30s plan generation with ±5% accuracy. UI handoff: Clean API (FastAPI) + React/Flutter frontend with real-time meal swap/lock, clear allergen tags, and modular components for scaling. I’ll deliver a working prototype, documentation, and a production-ready scaling outline (Docker + cloud deployment). Let’s define milestones and start. Nikhil....

Replicating the 'Freelancer trust loop' in a new industry requires a high-performance bidding engine and sub-second milestone updates. I'll build this using a real-time WebSocket architecture for live bid feeds, ensuring a frictionless experience for both agents and clients. Core features: - Secure, real-time bidding and offer acceptance - Milestone-based payment flow with dispute resolution dashboard - In-app chat with real-time push notifications - Web-based admin panel for user verification and fee management I've built similar marketplace platforms and can ensure a clean, scalable codebase. Do you have a specific payment gateway preference, or should I integrate Stripe Connect for global compatibility?

Hi there, I’m Shamshad and I’m excited to build your cross‑platform Freelancer-style app tailored for a different niche. I’ll start with a scalable architecture using native client stacks (SwiftUI for iOS, Kotlin/Jetpack Compose for Android) and a real-time backend (Firebase) with secure Stripe Connect payments, media storage, and robust role-based access. The plan includes a flexible job posting flow with media attachments, real-time bidding, milestone-based payments, dispute resolution, in-app chat, and comprehensive admin controls. I’ll ensure clean code, thorough API docs, and a Postman collection, plus a web admin panel with authentication, user verification, dispute handling and fee management. I’ll provide an intuitive hand-off guide and two weeks of post‑launch bug support. Proactive ideas will be shared during discovery to give you a strong start, such as category tagging for quick matching, push-notifications for critical events, and an MVP feature set to accelerate go‑to‑market. The approach: validate requirements, select proven tech stack (Swift/SwiftUI, Kotlin, Firebase, Stripe Connect), design modular components, implement secure auth via social logins, build real-time bidding and milestone flow, ensure media/uploads scale, implement chat and notifications, and deliver a maintainable admin panel with clear data models. I’ll work in tight sprints with frequent demos and a detailed API spec. Which KPI targets and launch timeline are you prioritizing for the MVP

Dear Client, This is a strong and ambitious marketplace idea, and I’d be glad to help you design and build a scalable cross-platform mobile application with a smooth bidding workflow similar to Freelancer but tailored to your niche. My focus would be on building a secure, real-time, and highly responsive system that works seamlessly across iOS, Android, and the web admin panel. My approach: Start by finalizing a clear system architecture (clients, agents, admin, and backend services) Use native iOS (Swift/SwiftUI) and Android (Kotlin) for high performance and smooth UX Build a scalable backend using Firebase or Node.js + real-time database for bidding, chat, and notifications Implement secure authentication (email, Facebook, Twitter login) I also like to add product thinking early so I can suggest UX improvements around trust, bidding clarity, and conversion flow to make the platform more engaging and efficient. A few questions : Which niche industry is this marketplace targeting? Do you prefer Firebase-only backend or a hybrid (Node.js + real-time DB)? Should payments support escrow per milestone or full upfront hold? Will agents need verification/KYC before bidding? Do you already have wireframes or should I design UX from scratch? Any preferred timeline for MVP launch? I can also suggest a phased rollout strategy to launch quickly and scale features afterward. Thank you!!!

Hi - Marketplace apps like this don’t drift on posting jobs, they drift when bids, accepted offers, milestones, payments, disputes, and chat all update different versions of the same transaction. A real user flow should be: customer posts a job with photos, videos, documents, and tags - agents receive notifications - agent places a bid or fixed price - customer accepts - milestone is created - Stripe Connect secures payment - chat opens - delivery, review, and dispute states stay tied to that job. This looks like a Freelancer-style app, but it gets inconsistent when payment state and job state are not controlled together. Milestone timing can lead to unexpected results in real use, so I handle it by designing the transaction lifecycle before building screens. The part to get right early is the marketplace state model, because it affects usability, correctness, fees, disputes, and launch safety.

ENGINEERING A HIGH CONCURRENCY BIDDING MARKETPLACE WITH SECURE MILESTONES For a marketplace requiring real-time bidding and secure milestone payments, I recommend Flutter or Kotlin/Swift paired with Firebase and Stripe Connect. To add the "initiative" you requested: I suggest implementing an AI-driven job categorization tool to help users post jobs faster and a "verified agent" badge system to build instant trust. At Plan D Studios, we bring 12+ years of experience in Mobile App Development and API Development, specializing in complex marketplaces and Database Design. My Technical Approach: Escrow Flow: Custom Stripe Connect integration for automatic milestone creation and a dedicated dispute resolution module. Real time Engine: Firebase driven bids and in app chat with voice message support. Admin Control: A robust web based SaaS dashboard to manage fees, verify agents, and oversee the dispute center. Deliverables: Clean architecture code, Postman collections, and 2 weeks of dedicated support. Everything is developed in house to ensure top tier performance and store approval. Would you prefer a 2- tep verification for agents (ID upload + manual approval) or an automated system based on social media history to speed up onboarding? Regards, Haider

Hi there, I have read your project requirement. You need a cross-platform marketplace mobile application similar to a freelancer model, with job posting, real-time bidding, milestone payments, chat system, notifications, ratings, and a web-based admin panel, built with scalable and secure architecture. We can develop a high-performance system using Flutter (or native Swift/Kotlin if preferred) with a robust backend (Node.js/Firebase), real-time bidding/chat, Stripe Connect for secure payments, and a clean admin dashboard for full control and moderation. A few questions to better understand your requirement: ============================================ Do you want escrow/milestone payments fully automated via Stripe Connect from the start? Should chat include real-time voice notes storage (Firebase/Cloud) or basic messaging in MVP? What is your expected user scale at launch (approx number of users/jobs per day)? Do you need multi-language and multi-currency support in phase 1? Best Regards, Srashtasoft Team
