About
I’m a full-stack engineer working with Java & Spring on the backend and SvelteKit on the frontend. I work on both sides, from APIs and application logic to the details of an interface.
My open-source projects include Discord event tools, documentation sites and Java libraries. I focus on clear interfaces and code that’s straightforward to maintain.
