How Infygen Built a Multi-Tenant SaaS Platform
A multi-tenant SaaS platform where many businesses run on one system safely — with subscriptions, team accounts, role-based access and analytics.
⚠️ This is a representative case study of a genuine build. Specific metrics, screenshots and client details are placeholders pending final, disclosable data.
The Challenge
A SaaS product has to serve many customers from a single system while keeping every customer's data strictly isolated. On top of that it needs subscriptions, team members with different permissions, and dashboards that stay fast as data grows.
The core requirement was a foundation that could onboard new businesses cleanly, bill them reliably, and never leak one tenant's data to another.
Our Solution
Infygen built a multi-tenant SaaS platform with an Angular dashboard, a Node.js/TypeScript backend, PostgreSQL for data, Redis for caching and background jobs, and AWS for infrastructure.
The platform handles the full SaaS lifecycle: sign-up, tenant provisioning, team invitations, role-based permissions, subscription billing and an analytics dashboard.
Key Features
- ✔ Multi-tenant data isolation
- ✔ Team accounts with role-based access
- ✔ Subscription & plan management
- ✔ Secure authentication (JWT)
- ✔ Admin & analytics dashboard
- ✔ Background jobs (reports, emails)
- ✔ Audit-friendly data model
- ✔ AWS cloud infrastructure
Architecture
Technology Stack
Challenges & Engineering
- Tenant isolation: every record is scoped to a tenant and queries enforce that scope, so one customer can never read another customer's data.
- Modular boundaries: tenant management, billing and authentication were built as separate modules so each can be reasoned about and scaled independently.
- Background processing: reports, exports and emails run on a queue off the request path, keeping dashboards responsive as tenants and data grow.
- Reliable billing: subscription state and usage were handled carefully so records stay consistent and customers are never double-charged.
