Kanban: Designing a Slick Drag-and-Drop Task Board

Overview

This Kanban board simplifies work organization. Users can customize vertical lists (Backlog, Todo, Doing, Done) and manage tasks using a fluid card system.

Engineering Challenges

State Synchronization: Preventing UI stuttering when moving cards between lists by using optimistic updates.

Drag Performance: Leveraged lightweight libraries ('@dnd-kit') to ensure smooth 60fps transitions on mobile devices.

Local Persistency: Instantly saves progress locally or pushes to the database asynchronously.
