Full-Stack Developer Needed to Build a Two-Sided Service Marketplace (Similar /Airtasker/TaskRabbit)

ob Title Full-Stack Developer / Agency Needed to Build a Two-Sided Service Marketplace (Similar to Upwork/Airtasker) Job Description Project Overview We are looking for an experienced full-stack developer or software development agency to build a robust, scalable, two-sided marketplace platform. The platform will connect service providers (taskers/freelancers) with clients (job posters), structurally similar to platforms like Airtasker, Upwork, or TaskRabbit. The ideal candidate must have a proven track record of building secure, database-heavy platforms with real-time features, secure payment processing, and intuitive user workflows. Core Key Features Required Dual User Roles & Profiles: Separate registration, onboarding, and dashboard workflows for Clients (Job Posters) and Providers (Freelancers/Taskers). Job Posting & Bidding Engine: Clients can post tasks with budgets, location (remote or physical), and deadlines. Providers can submit custom offers/bids. Escrow & Payment Gateway Integration: Secure payment handling (Stripe Connect or MangoPay preferred) supporting milestones, escrow holds, platform fee deductions, and payouts. Real-Time Messaging & Notifications: In-app chat between users before and after a hire, accompanied by push/email notifications. Rating & Review System: Mutual feedback loop after job completion to build platform trust. Admin Panel: A comprehensive dashboard for us to manage users, flag inappropriate content, resolve disputes, and view transaction analytics. Technical Preferences (Open to Suggestions) Frontend: React.js, Next.js, Vue.js, or Flutter/React Native (if proposing a mobile-first approach). Backend: Node.js (Express), Python (Django/FastAPI), or Ruby on Rails. Database: PostgreSQL or MongoDB. Hosting/Cloud: AWS, Heroku, or Google Cloud Platform. What We Are Looking For Prior experience building marketplaces, directory sites, or complex SaaS applications (portfolio evidence required). Strong emphasis on UI/UX best practices—the platform must feel modern and friction-free. Excellent communication skills and structured project management practices (Agile/Scrum, regular milestone updates). Screening Questions (Add these to the Upwork posting interface to filter candidates) Can you provide links to at least two complex web applications or marketplaces you have built from scratch? What was your specific role in those projects? Which payment gateway would you recommend for handling a two-sided marketplace escrow system in our region, and why? To ensure you've read this far, please start your proposal with the word "Marketplace-Ready".
