Hi, I'm Yang Ze! I'm most commonly known online as Level 51. In real life, I graduated from the National University of Singapore with a Bachelor of Computing in Computer Science and now work as a software engineer.

Pokémon

I've been playing competitive Pokemon for about half my life (some years more actively than others), including competing in the official Pokémon Championship Series since the first sanctioned tournament came to Singapore in 2015. I still play games now and then, but I'm mostly washed up nowadays.

Puzzles

I like solving puzzles and participating in puzzlehunts! I created, oversee, and write puzzles for Silph Puzzle Hunt (previously known as Smogon Puzzle Hunt). You can find some selected puzzles I've written here, including some of my favourite puzzles from the hunt.
