FlowDesk — Real-Time Project Management

Overview

FlowDesk is a collaborative project management ecosystem with Kanban boards, multi-workspace environments, real-time document editing, and Stripe subscriptions. Features Socket.IO and Redis Pub/Sub for instant cross-client notifications and live state sync.

The Challenge

Building a collaborative workspace that handles concurrent edits without race conditions, database deadlocks, or UI stutter. State sync must remain reliable even under poor network conditions.

Our Process

Researched operational transformation (OT) and conflict-free replicated data types (CRDTs). Settled on a Redis Pub/Sub backend with Socket.IO for state sync. Built type-safe APIs using tRPC to link frontend components and backend logic.

The Solution

Implemented real-time board updates, workspace presence indicators, inline collaborative document editing, and a premium tier powered by Stripe with automated invoicing.
