About me

A developer from Germany studying in England, passionate about building things for the web.

I started my programming journey in 2022, beginning with HTML and CSS before quickly discovering JavaScript and falling in love with the web platform.

After discovering Svelte and SvelteKit, I dove deep into the modern web ecosystem — TypeScript, TailwindCSS, databases, and DevOps. Today I build full-stack applications that are fast, accessible, and maintainable. Most recently, I've been focused on building Gust , using Rust.

I'm currently studying A-Levels in Computer Science, Mathematics, and Economics in England, while building Swingalytica.
