High-Level Full-Stack Engineer for SaaS Platform

Project Description

I am building a private, production-grade SaaS platform in the hospitality / transactional domain. This is not a prototype or no-code MVP—it is a real system that will process payments and manage multi-party workflows. The product scope, flows, and UI are already defined privately. I am looking for a senior full-stack engineer with a strong backend focus to implement the platform using Node.js (NestJS preferred), PostgreSQL, and Stripe (Stripe Connect strongly preferred). The work includes transactional workflows, role-based access (customer/vendor/admin), platform fees, vendor payouts, refunds, webhook handling, idempotency, failure recovery, admin and vendor dashboards, and country-specific tax/VAT logic. This role is not for WordPress, no-code tools, Flutter/mobile-first builds, or engineers learning payments for the first time. Please apply only if you have built a real SaaS or marketplace with payments in production and can briefly describe the system, how payments were handled, and your role in the backend architecture.
