About Graeme

Frontend-focused Fullstack Engineer with 3+ years building production web applications for high-traffic platforms, from a UN General Assembly website to SaaS products in the open-source space.
I specialise in React/Next.js, Vue/Nuxt, Svelte/SvelteKit, and TypeScript, with a strong eye for performance, accessibility, and clean component architecture. I've led legacy-to-modern migrations (cutting load times by 40%), built scalable design systems, and shipped under tight real-world deadlines.
Whether you need a fast, SEO-optimised Next.js site, a SvelteKit rebuild, or a full-stack web app with Node/PostgreSQL/MongoDB on the back end, I work autonomously, communicate clearly, and deliver production-ready code.
Based in Barcelona, fully authorised to work in Spain, available for remote projects across Europe.
