A very short origin story
From the world stage to the classroom, I care about rigorous thinking, clean execution, and helping strong teams become exceptional ones.
Gold medalist at IOI 2020, silver medalist at IOI 2021, and part of consecutive Asia-West champion teams at the 2024 and 2025 ICPC World Finals.
Students I taught earned 7 IOI gold and 9 IOI silver medals. As a tutor, I also mentored students to 2 IOI silver, 1 IOI bronze, and 5 INOI gold medals.
Ranked 70th worldwide when the source CV was updated in November 2025.
