AMEX needed a customer-friendly design that makes it easy to find out who's spending what on what, where. The admin side had to ensure privacy by hiding information that could potentially compromise confidentiality.
Working with a team of business and design experts, I researched the market, applied best practices, and went through several agile iterations, leveraging my significant experience in the space. I did concepting on the data visualization and most of the hands on work for the admin functionality.
The project was in trouble when we started, but I was able to turn it around by getting the basics right, while not getting lost in the details.
