SaaS Product Development
Multi-tenancy, subscriptions, roles and admin — the hard parts, done properly.
A SaaS product is a normal web app plus a set of hard problems: isolating every customer's data, billing each one correctly, controlling who can do what, and keeping the whole thing observable as tenants grow. Skip any of these and the product stalls exactly when it starts succeeding.
I build SaaS products on MERN and Next.js with multi-tenancy designed in from the first schema — tenant-scoped data, middleware-enforced isolation, Stripe subscriptions with webhook-driven state, and an admin layer that lets you support customers without touching the database.
I have written in detail about building a production multi-tenant SaaS on the MERN stack — tenancy models, middleware and billing patterns — in my journal, and I apply the same thinking to client products.
What you get
- Multi-tenant architecture: shared, schema-per-tenant or hybrid
- Tenant scoping enforced in middleware, not left to each query
- Stripe subscriptions: checkout, webhooks, plan limits, trials
- Role-based access control with invite and onboarding flows
- Tenant admin dashboards and usage views
- Environment, secrets and migration strategy from day one
Tools I work with
How we work
Tenancy model
We choose the tenancy strategy for your scale and risk profile, and write it down — changing this later is the most expensive refactor in SaaS.
Billing spine
Subscriptions are wired early — checkout, webhooks, plan gating — because everything from features to onboarding depends on billing state.
Product build
With isolation and billing solid, features move fast: the foundation makes ordinary development predictable again.
Operations
Monitoring, backups, audit trails and a support admin — so launch day is the start of operations, not the start of firefighting.
Common questions
Can you build an MVP without full multi-tenancy?
Yes, and sometimes you should — a single-tenant MVP with a clean upgrade path is often the fastest way to validate. I design the schema so the tenancy migration, when needed, is mechanical rather than a rewrite.
How do you handle Stripe webhooks reliably?
Signature verification, idempotent handlers, and treating the webhook as the source of truth for subscription state — with local records reconciled against Stripe rather than trusted blindly.
Can you join an existing SaaS team?
Yes — I work as an individual contributor on existing codebases, taking ownership of features end to end or specific subsystems like billing and tenancy.
