Full-Stack Developer for MVP Implementation -- 3

I'm looking for an experienced full-stack developer to implement the MVP end-to-end. I'll need a video call, so no scams here.

Overview
Clients submit coding tasks through a store-like request system. Each request becomes a project with clear lifecycle tracking, communication, time tracking, and weekly billing. The platform must support multiple roles: Client, Developer, and Admin.

Core Features (MVP)
Service Request & Project Creation
• Store-style service selection
• Structured task submission (requirements, priority, attachments)
• Automatic project creation after request/payment
Project Lifecycle Management
• Status flow (e.g. Received → Investigating → In Progress → Review → Completed)
• Progress updates and activity history
• Central dashboard per user role
Communication
• Dedicated chat per project
• File sharing and system messages
• Role-based access (client/developer/admin)
Developer Workflow
• Task assignment
• Hour tracking per project
• Weekly timesheet submission and approval
Billing & Payments
• Weekly billing cycles
• Client invoices
• Developer payout calculation
• Stripe / PayPal integration (or payment-ready abstraction)
Platform Foundations
• Secure authentication
• Role-based access control
• Scalable backend architecture
• Clean, maintainable codebase
Deliverables
• Working MVP deployed to staging/production
• Client, Developer, and Admin dashboards
• API and basic documentation
• Clear structure for future expansion
Technical Expectations
• Strong experience with full-stack web development
• Solid backend architecture (API-first)
• Experience with real-time features (chat, live updates)
• Payment integration experience
• Security- and scalability-aware development
Nice to Have
• Experience building marketplaces or SaaS platforms
• Familiarity with time tracking or billing systems
• Product-oriented mindset (not just feature delivery)
Engagement
The project already has completed 70%. This is a milestone-based MVP project with potential for long-term collaboration as the platform evolves.
Please include:
• Relevant past projects (especially SaaS / marketplace platforms)
• Rough timeline for MVP delivery
