Overview

The project

At Dart Design I design the Greytfinity app end to end: the flows, the screens and the design system they're built from.

Add who the app is for and what it lets them do.
The problem

What needed fixing

Write the real problem here: what users struggled with, and why it mattered to the business.

Add one real quote from a user interview.

Research

What we learned

How you learned about users (interviews, competitor reviews, usability tests, analytics) and how many of each.

Insight 1

One short sentence

What you saw, and what it meant for the design.

Insight 2

One short sentence

What you saw, and what it meant for the design.

Insight 3

One short sentence

What you saw, and what it meant for the design.

Design

Decisions

Two or three key decisions. For each one: the options, what you chose and why. Before and after screens work best.

The Credit Calculator

A Greytfinity feature I'm designing right now.

Add the question it answers for users, early sketches and what you'll test next.
Outcome

What changed

–Metric 1, such as task completion
–Metric 2, such as drop-off at a key step
–Metric 3, or feedback from the team or users
Reflection

What I learned

Two or three honest lessons, and what you'd do differently next time.
