SaaS Development

Multi-tenant SaaS, billing on day one

End-to-end SaaS builds with Stripe billing, multi-tenant auth, role-based access, onboarding flows, and admin dashboards — built to take real paying customers.

Why work with me

Most SaaS MVPs ship without billing, without admin tools, without invite flows. They look great on launch and break on first paying customer. I build with billing, tenancy, and ops from day one — because that's what survives contact with users.

What you get

Everything included in every engagement

No upsells. No surprise change orders. One scope, one price.

Multi-tenant from the data model up

Workspace/team scoping in Postgres with RLS, no leaky queries, audit log on every cross-tenant boundary, invite + role management.

Stripe billing wired correctly

Subscriptions, metered usage, proration, trials, cancellations, dunning. Webhook handlers are idempotent and signed. No silent revenue leaks.

Auth & RBAC

Supabase Auth or Auth0 with SSO, MFA, magic link, OAuth. Role-based access with permissions checked on the server, not the client.

Onboarding that converts

First-run wizard, sample data, checklist, contextual tooltips, and Intercom-style empty states. Activation is a feature, not a hope.

Admin & support tools

Internal admin to impersonate users, refund payments, view tenant health, and replay events. The tools your support team will need on day 2.

Marketing site + product on one domain

/, /pricing, /docs marketing pages sharing a design system with the product. Logged-in/out states handled cleanly.

How we'll work together

Predictable, written-down, no surprises.

  1. 01

    Pricing & tiers

    Pricing model, feature gating, and metering decisions before writing code. Wrong tiers = wrong product.

  2. 02

    Core flows

    Signup, invite, billing, cancel, upgrade, downgrade. Boring flows that drive 80% of revenue.

  3. 03

    Product features

    Whatever your app actually does — built tenant-aware from day one.

  4. 04

    Launch & iterate

    Closed beta with 5–10 design partners, instrument with PostHog, ship to public.

FAQ

Questions I get asked first

Stripe or Paddle?+

Stripe by default for control and ecosystem. Paddle when you want a Merchant of Record (handles VAT/sales tax globally). I'll recommend based on where your customers are.

How do you handle tenancy?+

Shared schema with tenant_id on every row, Postgres RLS for hard isolation. Schema-per-tenant only when there's a regulatory reason.

Can you migrate me off no-code (Bubble, Webflow)?+

Yes — common path. I keep your data model intact, recreate flows in Next.js, and migrate data with a one-time import script.

Do you handle SOC2 prep?+

I can wire the technical controls (audit log, MFA, access reviews, encryption) and recommend a vendor (Vanta, Drata) for the policy/evidence side.
