Sam Marxz

Full-stack Engineer

I'm Sam, a Frontend Engineer expanding into full-stack. Years shipping pixel-perfect interfaces taught me that great products aren't built in layers — they're built whole. Now I'm closing the gap: from the component to the API, from the design system to the database.
