Cornerstone is American Express' centralized big data ecosystem. It enables democratic access to data for all users, making it easier to work with data and drive innovation and growth across all of American Express' products.

During my time at Cornerstone UX, I focused on creating a more human experience for our analysts, scientists, and business stakeholders to help them better understand the data and make better decisions for the business.

This approach required too much expertise from most employees who wanted to work with data. As a result, many of them struggled to access the data they needed to make informed business decisions in a timely manner.

Cornerstone Dataprep aimed to solve this problem by simplifying the process and making it more accessible to everyone. I was asked to lead the UX for this project. I was asked to lead the UX for it.

The final result of the platform was a system that addressed the pain points of my users. I designed a usable and scalable interface, meeting technical limitations while prioritizing the user experience. The redesigned platform received positive feedback from both internal stakeholders and our returning customers.
