Mathnasium
I teach at Mathnasium, tutoring elementary and middle schoolers in one-hour math sessions a few times a week and working with a team of instructors to keep teaching strategy consistent.
3D Printing and Modeling
I'm the club leader of Sequoia's 3D Printing and Modeling club, which I founded in 2019 — drafting its charter, securing faculty support, and running meetings, agendas, and funding applications. I'm highly proficient in Onshape for CAD modeling and in slicing with Bambu Studio.
Cross Country & Track
I captain Sequoia's Cross Country and Track teams and lead the team's social media. I've built programs to strengthen culture, teamwork, and attendance, run the team's marketing, and earned All-League honors, course records, and three years of MVP honors from freshman through junior year.
Development Tools
I build and ship my own projects — including this site, RecovHR, and RunScore — using Claude Code, which I've been coding with for a while now, alongside Git/GitHub for version control and Vercel for deployment.
RecovHR
RecovHR is a heart-rate-reserve algorithm I built for individualized interval recovery, converting max heart rate, resting heart rate, lactate threshold, and workout type into the one number that tells you when you're recovered enough to go hard again. I wrote up the method in a paper and built a live threshold calculator.
RunScore
RunScore is a composite index I built that scores all 3,143 U.S. counties on the strength of their running culture, using CDC health data, race participation records, walkability scores, and fitness facility density. It correlates with home values, health outcomes, and school quality — a 10-point RunScore increase tracks with about $58,000 in higher median home value. I wrote up the methodology in a paper.
Music
I play saxophone, jazz and classical, with the San Carlos Jazz Band and the Sequoia Jazz Band, and I've released music on Apple Music and Spotify.
