Syncro Flow

Problem

Realtime collaboration tools often struggle with consistency, authorization, and scalability across multiple tenants.

Solution

Built a multi-tenant workspace with separate backend layers for persistence, authorization, and event broadcasting using WebSockets.

Architecture

• —Next.js App Router with Server Actions for validation
• —PostgreSQL + Drizzle ORM for data persistence
• —Pusher WebSockets for realtime event propagation
• —Role-based permissions and workspace invitations
• —Automatic polling fallback for WebSocket failures

Challenges

• —Ensuring mutation consistency across connected clients
• —Implementing secure multi-tenant data isolation
• —Handling WebSocket reconnection and fallback strategies

Outcomes

• —Production-ready realtime collaboration platform
• —Scalable multi-tenant architecture
• —Robust synchronization with automatic fallback
