The solution needed to address:
Multi-tenant architecture supporting unlimited organizations with custom domains.
Advanced role-based access control requiring granular permissions (ADMIN, MEMBER, BILLING).
Transparent billing system with automated cost calculation and usage tracking.
Scalable infrastructure capable of handling enterprise workloads.
Developer-friendly platform with modern tooling and comprehensive documentation.

š ļø Deep Dive
The platform features a monorepo structure with Turbo for optimized builds. The frontend uses Next.js 15 with React 19, featuring modern UI components and a seamless user experience.
The backend is powered by Fastify with TypeScript, featuring comprehensive OpenAPI documentation, JWT authentication, and a CASL-based authorization system. PostgreSQL with Prisma ORM ensures type-safe database operations.
Infrastructure is fully automated with Terraform, deployed on AWS EKS with auto-scaling (HPA), and includes a comprehensive CI/CD pipeline with GitHub Actions and OIDC authentication.
The billing system automatically calculates costs ($20/project + $10/seat) with real-time usage tracking and detailed reporting.
