Lyncfeed

Real-time B2B feed aggregator with role-based access control

---

Overview

Lyncfeed is a SaaS B2B platform that aggregates feeds from multiple sources in real time, with granular role-based access control (RBAC) for teams. Organizations can define who sees what, manage integrations, and monitor activity through a unified dashboard.

Architecture

├── apps/
│   ├── web/            # Next.js 15 + React 19 — frontend app
│   └── api/            # NestJS 10 — REST API + WebSockets
└── packages/
    └── types/          # Shared TypeScript types and interfaces

Monorepo managed with Turborepo + Yarn Workspaces. The frontend (apps/web) deploys to Vercel. The API (apps/api) deploys to a containerized environment on AWS.
