Multi-tenant SaaS platforms
A SaaS platform ready to add tenants, not rewrites.
SaaS problems appear later: permissions that leak data, subscriptions that do not match access, infrastructure that gets expensive as customers grow. I build multi-tenant platforms with authentication, billing and infrastructure designed so growth does not force a rebuild. You get a foundation you can keep shipping on.
What the platform ships with
Authentication and accounts
Sign-up, login, sessions and password recovery built on current standards, with tenant isolation from the first table.
Roles and permissions
Access rules per tenant, per role and per feature, so a customer only ever sees their own data.
Subscriptions and billing
Plans, trials, upgrades and recurring payments through Stripe or Mercado Pago, tied to what each account can use.
Multi-tenant architecture
A PostgreSQL schema designed for many customers, with the queries, indexes and background jobs that keep it fast.
Infrastructure for growth
AWS or Vercel with Docker, CI/CD, backups and monitoring, sized so early customers do not pay for unused capacity.
Problems that appear after launch
A customer can see data that belongs to another customer.
Billing says one plan and the product grants something else.
Every new feature forces you to touch the same fragile code.
Costs and slowdowns arrive before you have many users.
Answers to common questions about working together.
Yes. I start by reading the code and the data model, then fix the riskiest parts first, usually permissions or billing, while the platform keeps running. Migrations and deployments are planned so customers do not notice.
Data separation is decided at the schema level and enforced in every query, then covered by tests. For stricter requirements I can separate schemas or databases per tenant, though that raises cost and complexity.
It depends on scope: how many roles, which billing model and how much infrastructure you need. I give a scope-based estimate after a short call and split the build into stages you can approve one at a time.
