The Challenge.
The client needed to scale from 10 to 500+ tenants without rebuilding their infrastructure — their single-tenant Rails app couldn't support dynamic subdomain routing or isolated data.
Nexus was a promising B2B workflow tool stuck on a single-tenant architecture. Every new client required manual infrastructure provisioning, separate database instances, and custom deployment scripts. This bottleneck was killing growth.
We re-architected the entire platform as a multi-tenant Next.js application with row-level security, dynamic subdomain routing, and a self-service white-label configuration system that let clients brand the platform as their own.
Key Objectives
- 01Implement multi-tenant architecture with row-level security in PostgreSQL
- 02Build dynamic subdomain routing for white-label client portals
- 03Integrate Stripe Billing with usage-based pricing and subscription management
- 04Implement Auth0 with role-based access control across tenant boundaries
Engineered for Impact.
Multi-Tenancy
Row-level security in PostgreSQL ensures complete data isolation while sharing a single database for cost efficiency.
White-Label System
Dynamic subdomain routing with custom branding, logos, and color schemes configurable per tenant via admin panel.
Enterprise Auth
Auth0 integration with SSO, MFA, and granular role-based permissions across organizations and teams.
Usage-Based Billing
Stripe integration with metered billing, subscription tiers, and automated invoice generation for 500+ tenants.
Built on a
Modern Foundation.
We don't use page builders. We engineer robust software using the same tech stack as industry giants like Netflix and Uber.
