Design Systems @ Chick-fil-A | Lead Product Designer
I'm a Lead Product Designer with over 11 years in UX and design systems. I lead design systems for Chick-fil-A through CGI. I look after the component libraries and the governance product teams work under.
Before that I spent seven years at New Era Technology, growing from UX Designer to Senior UX Designer while consulting for Eli Lilly. I led the Lilly Design System's move from Sketch to Figma, a 30% gain in collaboration and design efficiency. I then helped rebuild it as LDS 2.0, with Figma Variables, design tokens, theming, and accessibility built in.
I work with product, engineering, and design ops to ship design systems and to standardize the process around them. I use AI in more of that work now, so teams move faster without a drop in quality.

Design System Lead

This case study explores the migration of Eli Lilly’s digital products to the Lilly Design System (LDS) using Figma, aiming to boost design consistency, streamline workflows, and enhance team collaboration.
Eli Lilly struggled with a fragmented, outdated design framework, causing inconsistent user experiences, workflow inefficiencies, and scalability challenges. A unified, modern design system was essential to improve their digital presence.



The LDS migration tackled inconsistency and inefficiency, paving the way for innovation at Eli Lilly. It demonstrates how a thoughtful design system, leveraging Figma, can drive collaboration and user-focused outcomes in healthcare.
