About me

I am a Ph.D. student studying combinatorics and optimization at the University of Waterloo under the supervision of Dr. Ricardo Fukasawa. I recently completed a M.Sc. in computer science at the University of British Columbia, where I was fortunate to be supervised by Dr. Bruce Shepherd. On the side, I make open source software for digitally processing audio and generating algorithmic music and visuals under the alias byte.observer. When not in front of a computer or whiteboard I can usually be found rock climbing, foraging for mushrooms, cycling, snowboarding, hiking or cooking.

Competitive programming problems

After competing for many years I was given the opportunity (thanks Zac!) to create original problems for a programming contest. It turns out that I enjoy making problems even more than just solving them! Most of my problems are available on Open Kattis, where anyone can try them out.

• Problems "Long Walk", "Maximum Fix", and "Undead or Alive" from the 2022 ACPC (Not yet on Open Kattis)
• Problems on the 2021 and 2022 Iverson Exam
• Problems "Similar Spacing" and "Travelling Caterpillar" from the 2022 UAPC
• Problems "Zoom," "Successful Zoom," "Solution Pollution," and "Tree Canopy Graphs" from the 2022 CCPC
• Problems "Wonky Pizza," "Beep Code," "Compression," and "Swapping Places" from the 2021 ACPC
• Problems "The Council" and "Which Bits?" from the 2021 CCPC
• Problems "Monochromatic Minesweeper" and "Wrapping Trees" from the 2020 ACPC
• Problems "Product Inspector" and "Lockpick" from the 2019 UAPC
