Build Global Freelance Marketplace App

I’m launching a new platform that lets clients hire top-tier marketing and business consultants on a project-by-project basis and gives those consultants everything they need to run an independent career from anywhere. I already have the concept and positioning—I now need an experienced product partner to turn the idea into a live, scalable application.

What I need built
• A responsive web app (and, if feasible, a cross-platform mobile build) where consultants create rich profiles, showcase portfolios, and bid on client-posted projects.
• Client dashboards that make it effortless to post a brief, compare proposals, and award work.
• Secure, real-time messaging so both sides can clarify requirements without leaving the platform.
• Milestone-based payments with escrow and release-on-approval logic to keep every transaction safe.
• A clean admin panel for me to verify new users, resolve disputes, and view platform analytics.

Key considerations
• Our initial niche is marketing and business consultants, so profile fields, portfolios, and search filters should speak their language (case studies, campaign metrics, growth KPIs).
• I’m open to modern stacks—React, Next.js, or Flutter for the front end; Node.js, Django, or Laravel for the back end; AWS or Firebase for hosting—so long as the result is secure and easy to expand.
• Security and compliance are non-negotiable: encrypted data at rest and in transit, role-based access, and GDPR-ready user controls.

Project scope
Phase 1: UX/UI wireframes and interactive prototype for core flows.
Phase 2: MVP build with user registration, project postings, messaging, and payments live.
Phase 3: Post-launch refinements based on user feedback and analytics.

If you’ve previously delivered a marketplace or SaaS product, tell me about it—links and stack details help. Let’s create the go-to hub where marketing consultants and their clients connect with confidence.
