The Challenge

Technical debt blocking growth.

A successful MVP had turned into a maintenance nightmare. The lack of multi-tenancy meant spinning up new databases for every enterprise client, and the rigid frontend architecture made releasing new features incredibly slow.

  • No multi-tenant architecture.
  • Hardcoded billing logic preventing tiered pricing.
  • 8-second load times on large data sets.
02

The Approach

Consolidate and containerize.

We redesigned the database schema for secure, row-level multi-tenancy in PostgreSQL. We decoupled the monolithic backend into modular Node.js services and integrated Stripe for automated subscription lifecycle management.

  • PostgreSQL row-level security for multi-tenancy.
  • Stripe Billing integration for automated invoicing.
  • React-based analytics dashboard with WebSockets.
03

The Solution

Built for enterprise scale.

The new platform allowed the sales team to onboard Fortune 500 clients instantly without engineering intervention. The streamlined architecture reduced load times to under a second and fueled a 220% growth in MRR over 6 months.

  • Instant client provisioning.
  • Zero data-leakage across tenants.
  • Massive reduction in server costs.
