Dewis

Overview

Dewis is a data-centric platform that surfaces complex information in a clear, actionable interface. The focus was on data presentation, filtering, and a highly usable table/list UI.

The Problem

Users needed a way to access, filter, and act on large datasets without feeling overwhelmed. The existing solution was cluttered and slow.

The Solution

Rebuilt the interface using React with a focus on progressive disclosure, smart defaults, and fast perceived performance through skeleton loading and optimistic states.

Challenges

• Handling large data sets efficiently without virtualisation libraries
• Designing clear data hierarchies that users can scan quickly
• Maintaining state coherence across complex filter interactions

Key Learnings

• Progressive disclosure is key for complex data UIs
• Skeleton loading improves perceived performance significantly
• Early collaboration with backend on API contract avoids rework
