Marketplace Platform – Admin Panel UI, Payment Integration & Marketplace Features (Long-term Work)

Marketplace Platform – Admin Panel UI, Payment Integration & Marketplace Features (Long-term Work)
PROJECT OVERVIEW

We are building a real marketplace platform step by step with a clean, production-ready architecture.

Phase 1 (VPS, SSL, DNS, deployment) is completed.
Phase 2 & 3 (backend core, user & admin APIs) are currently in progress.

We are now looking for a strong, fast, and cost-efficient developer to take ownership of Phases 4–7.

This is not a demo, not a tutorial project, and not a simple CRUD task.
We are looking for someone who understands real products and real workflows, not just code.
