Badminton Speed Meter, a stringing service, and this site all became more serious once someone besides me depended on them.
About
A little more
about me.
My name is Keshu Yang. I grew up in Shanghai, and in July 2021 my family moved to San Diego. I'm currently a student at Canyon Crest Academy, Class of 2027.
I am most interested in problems that sit between code, data, and the physical world. That is why one project became an app for estimating badminton speed, while another became a network analysis of air-quality coverage across San Diego County. I like the point where a technical method has to answer a real question.
Outside class, most of my time gets split between varsity badminton, research, music, stringing rackets, and taking photos. At school, I am secretary of a 98-member Physics Club and founded the STEM & Photography Club, which grew to 26 members. Mindful Moves became a way to turn chess into books, videos, and library resources for younger students.
One small thing that changed me was handing out flyers for my own stringing service at the rec center. Most of the people there were adults I did not know, and I am a fairly quiet person, so walking up to them took more effort than I expected. Since then, I have strung 200+ rackets for more than 50 players. When I am not doing any of that, I am probably looking for food I miss from home, playing Honor of Kings with friends, practicing piano, or taking photos somewhere.
Patterns that are hard to see.
Environmental data, model behavior, monitoring gaps, and measurement quality are the questions I keep returning to.
Shanghai, sport, and a camera.
Food from home, badminton practice, piano, and photography keep the work connected to an ordinary life.
Timeline
A few turning points.
A short path behind the site.
July 2021
Shanghai to San Diego
Moved from Shanghai to California. A lot changed at once, but food, music, and a habit of noticing small things stayed with me.
Fall 2023
Started high school
CCA became the place where badminton, clubs, physics, photography, and small projects started showing up in the same week.
Spring 2025
Badminton took more time
The sport turned into practices, matches, shoulder rehab, mostly singles, and eventually League Finals and CIF competition.
Summer 2025
Started putting work outside
I handed out stringing flyers, worked on Mindful Moves, and started testing the early idea for Badminton Speed Meter.
2026
Research became a through-line
UChicago Pathways in Data Science, air-quality network analysis, fuel-efficiency modeling, environmental chemistry, and climate informatics made data feel less like a class and more like a way to investigate the world.
