Hire a SaaS Developer
I build production multi-tenant SaaS end to end — tenant isolation, subscription billing, auth and RBAC, dashboards and the architecture to scale — with Next.js, Node/NestJS and PostgreSQL. Built by a senior engineer who ships and leads SaaS delivery, not a generalist agency.
SaaS lives or dies on a few early decisions: how tenants are isolated, how billing maps to entitlements, and how the schema absorbs growth without a rewrite. I make those calls deliberately up front and then build the product on top — so you can raise your next round without re-architecting the foundation.
What you get
- Multi-tenant architecture with real data isolation (RLS / strictly scoped queries)
- Subscription & usage billing (Stripe and PSP integrations), entitlements and plans
- Authentication, RBAC and tenant-scoped permissions
- Admin & analytics dashboards over your own data
- CI/CD, containerized deploys, and a production-readiness pass
How I work
We ship the thinnest legally- and commercially-valid version first — revenue and feedback sooner, risk lower.
Isolation model and the billing-to-entitlement mapping are locked in before feature work — they're the expensive-to-change core.
Typed end to end, queue-driven where it counts, with observability and a security pass before launch.
Shipped multi-tenant SaaS including Paylio (WPS-compliant payroll: tenant-isolated Postgres, RBAC, Stripe subscriptions) and a nine-product portfolio I lead delivery across. Scaled European commerce (E-Vignettes) to six markets and 18 locales with cent-accurate billing from a single codebase.

FAQ
How do you isolate tenant data?
In the data layer — row-level security or strictly scoped queries — with the tenant resolved once from the request context and threaded through. The client never scopes a tenant, so a bug in the UI can't leak another tenant's rows.
Can you build our MVP without painting us into a corner?
Yes — that's the point of scoping the smallest valuable slice. The MVP ships fast, but the tenancy, data model and billing boundaries are chosen so growth is additive, not a rewrite.
Do you handle billing and subscriptions?
Yes — Stripe subscriptions and usage billing, plans and entitlements, and multi-currency where needed. I've built cent-accurate billing across 18 locales and live PSP webhook pipelines.
