Marketing × Analytics × Triathlon
Hi, I'm Charlie! Right now I'm studying marketing and data analysis at Santa Clara University while leading marketing campaign analytics for a national nonprofit. Professionally, I like to build data-driven marketing systems to understand people's behavior. Outside of work, I train and coach triathlon, a discipline that shapes a big part of who I am.

About
My background and philosophy
Sammamish, WA → Santa Clara, CA
I'm originally from Sammamish, Washington. I studied Marketing and Data Analytics at Santa Clara University, where I also led the university's triathlon team. During that time, I balanced competitive training with internships and curriculum focused on using technology to solve problems.
I graduated in March 2026 and am now working as a Product Marketing Intern at Dayforce.
Outside of work, I continue to train and compete in long-course triathlon. I'm currently preparing for Ironman Santa Cruz and Ironman California.
Philosophy: Give. Grow. Deliver.
My approach to work has been shaped by the ideas of Adam Grant and John Doerr.
Give: From Adam Grant, I've been influenced by the idea of being a giver, helping others whenever you can, picking up the work people don't want to do, and doing what's best for the team at all times.
Grow: Also from Adam Grant, I've adopted the idea that reward is in growing. Try to seek growth over other things.
Deliver: From John Doerr I learned about OKRs, and have adopted this method goal setting in many areas of my life. I believe that qualifications and ambissions matter, but results matter more.
I try to bring these three big ideas into everything I do, whether professional or personal.
