About me

I'm Linus, from Qinghai. I'm currently a Grade 11 student. I love computer science and enjoy building interesting projects. I'm also a tech creator and like to share what I learn. You can find my channel "Linus Shyu" on Bilibili or YouTube, where I document my learning and creations.

Beyond code, I enjoy cycling and skateboarding outdoors, capturing life through the lens, or relaxing at the piano. As an informatics competitor, I was selected for NOI 2025 Winter Camp, the 2024 National Olympiad in Informatics in Provinces, and AdventureX 2025. These experiences deepened my interest in software development and theoretical computer science, and strengthened my goal to pursue a PhD in CS at MIT. I hope to build tools and apps that work for me and help others with similar journeys.

Right now I'm developing and shipping an app called FeelFlow on the App Store with Swift. I'm also learning front-end to build beautiful, interactive pages. To broaden my technical horizons, I'm getting started with Rust—recreating the NeoFetch open-source project and exploring Linux internals—and rethinking what I could build with Solidity that truly resonates, beyond crypto alone.
