Hey! I'm Kirill Tregubov, a 24 year-old software developer based in Canada. I specialize in TypeScript and spend most of my time building CLI tools and modern web, mobile and desktop apps using React. My preferred tech stack also includes React Native, Tauri (Rust), Vite, TailwindCSS, Node.js and PostgreSQL. I graduated from the University of Toronto with an Honours Bachelor of Science in Computer Science. I'm passionate about open-source software, interface design, science fiction and astronomy. I use arch btw.

If you want to get in touch, you can email me at [email protected].
