Hi, I’m Xavier Cooper, a full-stack web developer and frontend specialist with a passion for building performant, accessible, and visually compelling digital experiences. I love shaping UI with Svelte/SvelteKit, React, and TypeScript, and I bring hands-on expertise in 3D graphics and motion using Three.js, WebGPU, and Blender. With a physics-and-design mindset, I engineer immersive interfaces that are robust, modular, and delightful to use. I’ve led end-to-end product development across startups and agencies, including MangoSweat (a personal growth brand with Web3-enabled features) and EverySpec (a web engineering agency). I’ve shipped Web3-enabled platforms, built scalable frontends, implemented real-time data flows, and mentored teams. I thrive in high-ownership environments and am excited by AirGarage’s mission to repurpose urban space through software.…
