Percy Wu.
Thinking in systems.
Building for people.
From commercial game engines to software running across three hotels. I turn complex rules into tools and experiences people can use.

01 / What I can do
What I build.
How deep it goes.
I build software close to the people who use it.
Commercial C++ game engineering at Tencent taught me how large systems fit together; running IT and digital operations for three Sydney hotels taught me what those systems have to survive.
Today I deliver working software fast with AI tooling under my own review, keep the infrastructure it runs on healthy, and bring a data-science background to the numbers behind it.

The work.
The thinking behind it.
Production platforms, game systems and verified mathematics. Each project opens up the problem, my contribution and the decisions that shaped it.

My best work starts with understanding how a system is actually used.
Commercial game teams taught me to think across code, assets and network state. Running digital operations brought me closer to the people relying on those decisions every day.
Today I bring both perspectives to software: model the rules, make the interface clear, verify the difficult cases, and follow the work into production.

An eye for
how things feel.
Before software, I studied environmental design. I still make room for 3D visualisation, drawing and the details that make an interface feel considered.
