Senior Next.js + Prisma + Stripe Developer Needed to Deploy Existing Multi-Vendor Marketplace MVP

I already have a **premium multi-vendor marketplace MVP fully built locally** and I need a senior full-stack developer to **productionize, secure, and deploy it live**.

This is NOT a build-from-scratch project.

The codebase is already complete and built with:

## Current Stack

* Next.js 15
* React
* TypeScript
* Tailwind CSS
* Prisma ORM
* PostgreSQL-ready schema
* REST API routes
* Stripe + Stripe Connect placeholders
* Vercel-ready architecture

## What is already built

* premium homepage
* dynamic product pages
* buyer auth pages
* buyer dashboard
* checkout flow foundation
* seller dashboard
* payout foundation
* seller upload wizard
* public seller storefronts
* marketplace search + categories + filters
* admin moderation dashboard
* responsive luxury UI
* mobile layouts
* Prisma schema structure

## Your job

I need you to work from the **existing codebase**, NOT rebuild it.

Main responsibilities:

1. review current codebase
2. back up to GitHub
3. deploy to Vercel
4. connect custom domain: **CodeScripts.one**
5. connect production PostgreSQL DB
6. replace placeholders with real services:

* Stripe payments
* Stripe Connect payouts
* authentication
* secure file storage
* protected downloads
* email notifications
7. QA buyer, seller, and admin flows
8. fix launch-critical bugs
9. prepare for beta launch

## IMPORTANT

Please do NOT bid if your first recommendation is to rebuild from scratch.

I need a senior developer who is comfortable:

* improving an existing Next.js codebase
* deploying SaaS/marketplace apps
* Prisma migrations
* Vercel
* Stripe Connect
* secure file ownership/downloads

## Please include in your proposal

* similar SaaS or marketplace work
* Stripe Connect experience
* Vercel deployment examples
* milestone-based cost
* realistic timeline
