Frontend developer building interactive 3D web experiences with React, TypeScript, and Three.js.
Russian FederationWhat I'm looking for
I’m a frontend developer with full-cycle experience, from interface design to production infrastructure. My core stack is React and TypeScript, and my strongest side is interactive 3D graphics in the browser with Three.js.
I’ve delivered end-to-end features, including fullstack work where I handled the server side in Go. At Lstore.graphics, I built interactive 3D rendering in React + Three.js, organized state with Redux Toolkit + RTK Query, maintained reusable UI documentation in Storybook, and helped ship a CDN and SEO improvements that reduced asset load time by roughly two-thirds.
