Who Am I?

Basic Info

My name is Peisong Xiao. I also go by Paul when that makes conversation easier.

I am a University of Waterloo student in Computer Science with a minor in Combinatorics and Optimization. Most of the work I am drawn to sits near infrastructure, networking, systems design, and the practical details that make technical platforms reliable at scale.

Where I Come From

I am from Fujian, China, a place shaped by coastlines, mountains, humidity, seafood, rice, and movement. That environment matters to how I think about technology: dense systems, hard constraints, and a lot of life happening at once.

What I Spend Time On

I like building things that make abstract ideas concrete. Sometimes that means drafting a side project, sometimes it means refining a workflow, and sometimes it just means going for a walk with a camera and letting a line of thought settle into place.

Outside of class and internship work, I keep coming back to origami, cooking, music, reading, and small systems of my own design. Professionally, I care most about infrastructure and performance-sensitive computing. Networking in particular feels underrated to me: it is one of the layers where careful design decisions still have a direct, physical impact.

What This Site Is For

This site is being rebuilt as a static-first personal space. The manual pages and photo archive come first. The repo-backed writing and design documents will come back later through a cleaner automation pipeline.
