About
Hi, I'm Clark Hayashi.
I'm a Business Analytics and Marketing graduate from Seattle University with a minor in Japanese, born and raised on Oahu.
People hand me something new or unfinished and I work out how to run it. It started behind a register at the Navy Exchange in Honolulu. At Seattle U I officiated intramural sports for four years and grew into running the program. I helped found a student credit union initiative from nothing. And I spent a summer as one of the first AI interns at Bank of Hawaii.
Sports run through all of it: co-captaining my high school varsity basketball team, officiating and managing intramural leagues, and scrimmaging against a D1 women's basketball team as a practice player. I ask who will actually use the thing, I over-communicate rather than assume, and I finish what I start, a habit Scouting drilled in early.
AI is a real part of that now and I use it every day. The hard part is almost never the model. It is knowing the business well enough to ask the right question and being willing to say when an answer is wrong. That judgment came from the messier jobs, not from the tools.
Tools
Excel, Power BI, Tableau; working knowledge of Python, SQL, and R.
Photoshop, Premiere Pro, and CapCut.

Seattle University Recreation
Intramural Sports Official → Manager
2022 to 2026
Four years in the program. Started as a student official in fall 2022 and grew into Intramural Sports Manager senior year. A lot of the officiating was for law students older and bigger than me. You make the call in half a second and then stand behind it while grown adults yell about it. It also put me in front of people from all walks of life I would never have met otherwise. Named 2026 Intramural Sports Manager of the Year (1 of 11 managers). Trained and mentored 40+ officials across a program that drew 648 players in 2025, ran operations, scheduling, and conflict resolution, and produced digital media with 3× the engagement of standard department posts.

Rooted perspective
I grew up in Hawai‘i, where community isn't a value statement; it's just how things get done. Seattle is where I learned to work: analytics and marketing classes, a student credit union, four years of intramural sports. A semester at 上智大学 (Sophia University) in Tokyo and a study tour through Tuscany stretched that further. Being the person who doesn't fully speak the language or know the customs teaches you to pay close attention.
What I'm working on now
- Applying for marketing, analytics, sports, global business, and program management roles
- Making listing photos, reels, and social posts for a real estate business in Honolulu
- Studying Japanese for the JLPT N3 in December 2026
