The Problem

Magister was losing users to modern competitors. Its "legacy friction"—a cluttered 90s UI—generated high churn and massive overhead for technical support.

The Solution

A redesign focused on centralized search architecture, optimized reading patterns, and a frictionless onboarding flow that prioritizes professional authority.

Flow 01

Frictionless Access & Conversion

I redesigned the entry journey to convey security and authority. By removing unnecessary fields and focusing on visual clarity, we optimized the activation time for new users.

Login Screen

Login Portal: Focused on conversion and security.

Sign Up Screen

Registration: Reducing cognitive load during onboarding.

Recovery Flow

Password recovery management: A "self-service" flow designed to deflect support tickets.

Flow 02

Intelligent Search Architecture

The heart of the product. We moved from a cluttered search to a results-oriented interface. I implemented collapsible side filters to maintain focus on the content.

Filtered Results

Design Insight: The use of skeletons and instant feedback on filters reduced perceived loading time by 25% during usability testing.

Flow 03

Technical Reading Experience

Lawyers spend hours reading dense documents. The redesign prioritized visual comfort, scalable typography, and a clear hierarchy for court rulings and summaries.

Document Visualization

Detailed View: Contrast and spacing optimization for prolonged reading sessions.

Flow 04

Data Integrity & Security

In compliance with data protection regulations, I created a security portal where users have total control over their data, active sessions, and two-factor authentication.
