My Interests and Strengths
Math
I am immersed in competitive math regarding various competitions such as the AMC 8, Caribou, Mathematica, Gauss, Canada Jay and BCC. Currently, I am working towards learning more advanced high school competitive math to excel in competitions like the AMC 10. Inspired by my sister Grace, my goal is to triumph at an international level.
Programming
My experience in programming spans both competitive programming and project development. While I study competitive programming techniques and solve problems on DMOJ (check out my resources hub!) to prepare for competitions such as the CCC, I work on projects such as this one (check out my portfolio for other projects) to expand my skills in multiple langauges and interfaces.
Science
My experiences in the LTSC, or Let's Talk Science Challenge, fueled by a yearning to understand the world, have led to my interests in Physics, Biology, and Chemistry. I hope to expand my knowledge of various scientific concepts with the goal of participating more in competitions in the future.

Mental Math Tricks Courses
Pursued my passion for Math in an interactive and educational application that taught users mental math tricks with varying difficulty. As enthusiasm for Math has been declining over the years due to students lacking a passion for the subject, I added more fun and appealing courses rather than tedious and boring lessons. I created MMT using HTML, CSS, and Javascript and it now has 5 courses each with a detailed lesson article equipped with examples, a post-lesson quiz, and a daily practice session (which is random and goes on forever)!

WRAB (Walking, Running, And Biking)
For Ignition Hacks 2024, I collaborated with Grace, Jessica, and Olivia in a team of 4 to create WRAB, an application built to enhance your outdoor physical activities. Wrab provides a built-in route generator given a start/end point, a path creator given a start point and distance desired, and a map with markers for users to note down the location of water fountains, washrooms, and other hotspots. The maps use TomTom API and the routes are generated with the help of Spherical Geometry.

My Blog
2/17/2025
After multiple large snowstorms which resulted in an accumulation of more than 60 centimeters of snow in my backyard, I employed the help of my sisters to create a mini quinzee. However, we are still waiting for the snow to become packing snow so that we can finally obtain a completely strong structure. This led me to wonder, what makes snow change form?
Science
