Multi-Tenant SaaS Management & Billing Hub
An enterprise-grade SaaS application designed from the ground up for high concurrency and strict data isolation. Built with Next.js App Router and PostgreSQL row-level security (RLS), the platform powers recurring subscription billing, seat management, custom branding per tenant, and usage-based metric aggregation.
Business & Technical Friction
- Strict data isolation requirements between enterprise tenants in a shared database schema.
- Complex hybrid pricing models including flat platform fees, per-seat tiers, and metered usage overages.
- Need for instantaneous dashboard telemetry and sub-second report generation under heavy load.
Architecture & Implementation
Architected a Next.js full-stack system with Prisma schema multi-tenancy and Stripe webhook synchronization. Implemented server-side cached aggregations and edge middleware for ultra-fast tenant routing and authentication.
