Enterprise SaaS Platform

Designed and built a full-stack SaaS platform with multi-tenant architecture, role-based access, real-time dashboards, and Stripe billing integration.

The Challenge

The startup had validated their product idea with a prototype but needed a production-grade platform that could handle enterprise security requirements, multi-tenant data isolation, and complex billing scenarios. Their MVP was hitting scaling walls at 200 concurrent users.

Our Approach

  1. 1

    Architected a multi-tenant system with row-level security in PostgreSQL and tenant-scoped API middleware

  2. 2

    Built role-based access control supporting custom permission sets per organization with audit logging

  3. 3

    Integrated Stripe billing with usage-based metering, annual contracts, and automated invoice generation

  4. 4

    Deployed on AWS with auto-scaling, multi-region failover, and real-time monitoring dashboards
