02 / APPROACH

Make the system before polishing the surface.

The interface becomes clearer when product intent, technical constraints and user movement are resolved together.

  1. 01

    Frame

    Clarify the problem, the audience and the decision the product needs to support.

  2. 02

    Model

    Turn flows, states and dependencies into a system that can be explained and maintained.

  3. 03

    Design

    Use hierarchy, interaction and visual language to make that system understandable.

  4. 04

    Build

    Implement the experience with the details, states and constraints that make it real.

03 / A LITTLE CONTEXT

A path through
words, systems
and software.

Marketing taught me to think about the message. Product work brought that thinking into the interface. Engineering lets me carry it through to a working experience.

COMMUNICATION & CAMPAIGNS

Finding the story.

Copy for ordinary campaigns, reporting and video participation, alongside project management, at Universidade Candido Mendes. Ordinary campaign layouts were created by others. Strategy, base wireframes, scripts and copy with the Fallen Store team; João Vitor finalized the layouts.

UX & INTERFACE SYSTEMS

PRODUCT ENGINEERING
