👤Profile
I'm a university student majoring in Information Engineering. I build and publish free web tools using the programming skills I've learned — React, Next.js, TypeScript, and more — to make everyday tasks easier for everyone.
🎯Mission
My goal is to provide fast, safe, and multilingual web tools that streamline everyday workflows. I turn what I learn in university into real products that are useful to people around the world.
