I turn data, ideas, and operations into clear decisions

I like taking scattered information, finding the pattern, and explaining what matters in plain language. I use analysis, dashboards, and practical AI tools to get there.

Honolulu

Where I'm from

~2022

I grew up on O'ahu, where community isn't a value statement; it's how things get done. Punahou basketball and a varsity co-captain year, a 199-hour Eagle project rebuilding a library, and a first job ringing up military families at the Navy Exchange.

What I Bring

Five lanes, one job: make things clearer. The work above is the evidence.

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.

How I Work

01

Analyze

Start with the decision someone actually needs to make, then dig into the messy data, workflows, and business questions behind it. If the output doesn't change a decision, it isn't done.

02

Translate

Turn findings into clear stories: dashboards, decks, and recommendations in plain language. Data explains what's happening; talking to people explains why.

03

Build

Ship practical systems, reporting, and workflows teams actually use. A dashboard a team opens twice a week beats a perfect model nobody touches.

I co-founded a student credit union initiative that won $22.5K across two business plan competitions and spent four years helping run Seattle U's intramural program. The thread through all of it: helping teams make sense of messy problems and turn ideas into action.
