Aloha, I’m Magellan McCartney — a Data Analyst and Web Consultant passionate about connecting insights, creating relationships, and improving business performance through data analytics, marketing technology, and storytelling.
With a background that bridges analytics, technology, and coaching, I love creating systems that help people see meaning in their data — whether through marketing dashboards, business development, or educational storytelling.
My Story (Paris → Hawai‘i Journey)
I left Hawai‘i with a curiosity for language, culture, and technology that led me to Paris, where I studied French language and culture while earning my Bachelor’s degree in Computer Science at the American University of Paris. Motivated to go further, I pursued a Master’s degree in Data Science, blending technical expertise with creativity and analytics.
During my studies, I gained hands-on experience in Paris’s fast-paced tech and marketing environment, working full-time at Stormcast Cinema as a Data Analyst and later at Optimize Matter as a Data Marketing and Cloud Consultant, where I developed data solutions and implemented analytics systems for major European clients such as Electro Dépôt, EDF, and Omnes Education. I developed a passion for consulting because it allowed me to form meaningful relationships with clients—putting humans first in a data-driven world—while working on diverse projects that strengthened my technical and interpersonal skills and led me to earn certifications in Google Analytics and SQL.
Now back home in Hawai‘i, I bring a global perspective to local innovation — but my journey of exploration and learning is far from over.
Professional Focus
As an analyst, I focus on transforming complex marketing and performance data into meaningful stories that drive smarter decisions. My approach combines technical precision with creative problem-solving, ensuring that data not only performs — it communicates.
I’ve designed and deployed analytics systems across marketing, automation, and website performance — building frameworks that connect technology, insight, and strategy. Curious to see how data storytelling comes to life? Explore my interactive marketing and business intelligence dashboard here.

Beyond the Data
Outside of analytics, you’ll find me coaching volleyball at Punahou School, where I am the Assistant Defensive Head Coach for the Girls’ Varsity program and Head Coach for a Junior Varsity Boys’ team.
Before returning to Hawai‘i, I competed at the Pré-National level in France and earned first-place finishes in Series 3-100 tournaments within the Île-de-France region.
I also volunteer with Stars Above Hawai’i— sharing Hawaiian celestial navigation and astronomy with visitors and local communities.
