SG SaaS Starter Pro

Problem

Building a SaaS product from scratch requires repeatedly implementing core modules such as authentication, users, roles, permissions, dashboards, organizations, analytics, logs and notifications before work can begin on the product's specific business functionality.

Solution

A reusable full-stack architecture was built with separate Next.js frontend and Node.js/Express backend applications, MongoDB persistence, JWT authentication, organizations and workspaces, advanced roles, permission helpers, dashboard analytics, activity logs, and persistent and real-time notifications through Socket.IO.
