Senior Full-Stack Engineer for SaaS Platform

I'm building a private SaaS platform in the hospitality and transactional domain and need a senior full-stack engineer/s experienced in developing real systems with payments.

Scope of work
NOTE: If your application is generic, copy-pasted, or avoids specifics, I will not reply.

If you’re a strong engineer who likes owning real products, this will be a good collaboration.
The product includes:

Multi-role users (customers, vendors, admin)

Transactional workflows (orders, status changes)

Online payments with platform fees

Vendor dashboards & admin analytics

Country-dependent tax / VAT logic

Production-grade backend architecture

The product scope, flows, and UI are already defined privately.
I’m looking for a senior full-stack engineer who has built real SaaS systems with payments, not prototypes.

What This Role Is NOT

No Wix / Webflow / Bubble / no-code
No WordPress
No MongoDB-only architectures

Additional information
We're seeking long-term collaboration with clear milestones, direct communication, and high code quality expectations. We value ownership of your work.
