I'm a CS student at MIT, currently interning on the engineering team at Liquid Trading, where I'm building the notification infrastructure.
I can be reached at jzhe at mit dot edu.
Here's my CV.
Before
Previously I interned at AbbVie, where I worked on statistical analysis of proteomics and evaluating frontier deep learning models trained on PK data.

You're looking at it. One hand-written HTML file, no framework and no build step, served from Cloudflare. The sky is drawn at load time from a seed, so every refresh gets a different one, and the stars are placed to stay clear of the column you're reading. Now and then a few of them whose twinkles line up get joined into a constellation, which holds for a moment and then fades. The moon in the corner is drawn in whatever phase it is actually in today.

A browser co-op sci-fi roguelike we built at HackMIT 2026 (Entertainment track). Each player types one sentence, and Claude turns them into a world: its rooms, monsters, physics rules, and the notes the dead left behind. Then you fight through it together. The model writes validated JSON, never code.
Some combinatoric games that I made on codeforces linked here. You'll need a codeforces account to view them.
I have plans to keep authoring more problems, either for codeforces, usaco, or ioi, which I'll post here if they make it on.
