About me
I came to programming while finishing a degree in Business Administration — which means I care as much about the goal behind a project as the code itself. My core stack is Next.js, Sanity and Shopify with TypeScript, and I love the moment a tricky problem finally clicks into place.
As a freelancer I work closely with clients from first sketch to launch — keeping communication clear and shipping things that are fast, accessible and genuinely nice to use. When I'm not coding I'm usually gaming, travelling, or picking up something new (lately, the guitar).
