Traveling
I love planning routes, hunting for local food, and collecting small “wow” moments from each trip.

Welcome to my portfolio! I’m Zhihui Xu — a developer who enjoys building practical web apps and games.I build full-stack products: dashboards, APIs, and web experiences — from the first prototype to deployment. This site is my playground: projects, a stock dashboard, and a mini-game challenge — all built with Django templates.

About Me
Outside of coding, I recharge with travel, stargazing, and pets (more of a dog person, but cats are cool too).
Stargazing
Stargazing resets my brain. I like calm nights, big skies, and spotting constellations.
Cats & Dogs
I’m more of a dog person — but I appreciate the cat attitude. Both make life better.
