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 O‘ahu.
I'm a versatile operator. 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.
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.

What I Bring
Analytics + Data
I structure messy data into dashboards, reports, and recommendations a team can act on. Core tools: Excel, Tableau, Python; currently deepening SQL.
Marketing + SEO
Hands-on measurement work: GA4, Google Tag Manager, Search Console, UTM strategy, local SEO, and content performance. Currently applied to real estate lead tracking.
AI-Enabled Workflows
I use AI to accelerate research, analysis, prototyping, and documentation while keeping the business question, source quality, and final judgment human-led.
Leadership + Operations
Proven across organizations, from Scouts BSA to UREC to SUCUI: I've run programs, trained 40+ officials, and built the schedules, reporting, and playbooks that help people execute better.
Visual Communication
I turn complex work into clear artifacts: dashboards, decks, short-form video, and case studies people actually understand. Tools: Photoshop, Premiere Pro, Final Cut Pro. This site included.

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. 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.
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. None of this shows up on a dashboard, but it shapes how I build one. 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. The question underneath every project stays the same: how do I make this clearer, more useful, and more human?
