Multi-Tenant SaaS Development
I design and build production multi-tenant SaaS end-to-end — tenancy and isolation, billing, auth and RBAC, dashboards and the architecture to scale — with Next.js, Node/NestJS and PostgreSQL. Built by a senior engineer who ships, not a generalist agency.
From a clean architecture to a product real businesses run on: multi-tenant data isolation, subscription billing, role-based access, analytics, and a deployment pipeline that lets you ship safely.
What's included
- Multi-tenant architecture with real data isolation (RLS / scoped queries)
- Subscription & usage billing (Stripe and PSP integrations)
- Authentication, RBAC and tenant-scoped permissions
- Admin & analytics dashboards
- CI/CD, containerized deploys, and production hardening
How I work
We define the thinnest version that delivers value, so you ship and learn fast.
Tenancy, data model and async boundaries decided deliberately up front — the expensive-to-change parts.
Typed end-to-end, queue-driven where it counts, with a production-readiness pass before launch.
I lead a five-person team across a nine-product SaaS portfolio and have shipped multi-tenant systems including WPS-compliant payroll (Paylio) and payment-analytics platforms over live PSP webhook data.

FAQ
How do you handle multi-tenant data isolation?
Isolation is enforced in the data layer — row-level security or strictly scoped queries — with tenant context resolved once and threaded through. The client never scopes a tenant.
Can you work with my existing codebase?
Yes. I start by understanding the current architecture and follow its patterns, improving the parts I touch rather than rewriting blindly.
