/ About
A bit about me
I combine a physics background with computer science training to build thoughtful, data-informed web products.
I'm Junyu Yao, currently pursuing a Master of Computer Science at Rice University. Before that, I studied Physics with a minor in Business at UT Austin.
- I build full-stack applications using technologies like Python, JavaScript, React, Next.js, Vue, Node.js.
- Previously worked as a Web Engineer at iFlyBank and Tech Lead at UTCSSA, where I developed platforms like GalaGate and YTubeDB used by real communities.
- At SpectraCell Laboratories, I improved data pipelines and reporting as a Data Analyst; at Radical AI, I contributed to AI-powered tools.
- I enjoy working in collaborative, fast-paced environments where I can own features end-to-end — from idea and design to deployment.
- Outside of coding, I like soccer, gaming, and hackathons, where I’ve been recognized for creative, practical projects.
