Engineering,
from signal to system.

I'm Wallace Gao. I build embedded systems, digital hardware, and networks by connecting careful design with hands-on testing.

How I work

Understand the system.
Build with intention.
Test what matters.

My projects move between software and hardware - from a C++ probability model to timer-driven sensor firmware and a complete routed network. I'm most engaged when I can see how every layer contributes to the result.

Selected projects

Built, measured, understood.

Each project opens into a detailed case study covering the idea, technical approach, and what I learned.

About

Curious across every layer.

I'm a Computer Engineering Technology student at Rochester Institute of Technology, graduating in May 2027.

My coursework spans digital systems, microcontrollers, circuits, electronic devices, computational problem solving, and networking. I enjoy translating those fundamentals into working systems I can inspect, debug, and improve.
