SaaS Application Development
A SaaS product has a few non-negotiable pieces before it can charge anyone money: accounts, billing, and a way to keep one customer's data separate from another's. I build that foundation alongside the actual product features, so the MVP is a real multi-tenant application rather than a demo that needs rebuilding once the first paying customer signs up.
The goal is shipping something real fast without accumulating the kind of technical debt that makes the second version of the product harder to build than the first.
Problems This Solves
- arrow_rightNeeding to validate a product idea with paying customers without over-building before knowing if it's wanted
- arrow_rightA prototype that has no real account system, billing, or data isolation between customers
- arrow_rightUncertainty about how to structure a multi-tenant data model so customers can't see each other's data
- arrow_rightWanting to add subscription billing without building a payments system from scratch
What's Included
- checkAuthentication and account management
- checkMulti-tenant data architecture with proper isolation
- checkSubscription billing via Stripe
- checkCore product features scoped to what proves the concept
- checkAdmin views for managing customers and subscriptions
- checkDeployment and monitoring setup
How I Work
- Scope the MVP down to the features that actually test the product's core assumption
- Design the multi-tenant data model — usually a tenant/organization ID on every row, enforced consistently
- Build auth, billing, and the core feature set together, since they're interdependent
- Add the admin tooling needed to support early customers without a full internal dashboard
- Launch, then prioritize the next build based on real usage rather than guesses
Technology Stack
- arrow_rightNext.js / React
- arrow_rightNode.js
- arrow_rightPostgreSQL / Supabase
- arrow_rightStripe billing
- arrow_rightTypeScript
- arrow_rightVercel or AWS deployment
Suitable For
Founders with a validated idea who need a real product to put in front of paying customers, and existing SaaS products that need a technical partner to keep building features without an in-house engineering team yet.
Frequently Asked Questions
How long does a SaaS MVP take to build?add
It depends entirely on scope — the honest answer is that timeline should be driven by cutting features to the minimum that proves the idea, not the other way around. I'll push back on scope that doesn't need to exist in version one.
How do you handle multi-tenancy?add
Typically a shared database with a tenant/organization ID enforced on every table and every query — simpler to operate than separate databases per customer, and sufficient for the vast majority of SaaS products until they reach a scale that needs isolation for compliance reasons.
Can you add Stripe billing to an existing product?add
Yes — subscription plans, metered billing, upgrade/downgrade flows, and webhook handling for payment events (failed charges, cancellations) can be added to an existing app without a rebuild.
Do you build the marketing site too?add
Yes, usually as a separate Next.js route or app from the authenticated product, since the marketing site needs to be fast and indexable while the app itself doesn't.
