✦ Open to new opportunities

Hi, I'm Pei-Wen Tang

Software Engineer & AI Specialist

MS Computer Science @ USF. I build scalable full-stack systems and AI-powered applications — from distributed infrastructure in Go to computer-vision pipelines and modern React interfaces.

About Me

Building things people
love to use

I'm a full-stack developer with a passion for crafting seamless digital experiences. My journey started with curiosity about how things work on the internet and grew into a career building them.

I specialize in React and TypeScript on the frontend, with GO, Python, Java, C++, and cloud-native services on the backend. I care deeply about performance, accessibility, and the tiny details that separate good software from great software.

When I'm not coding, I'm exploring the world, hiking, playing basketball or learning new technologies that draw my attention.
