I'm a Mechanical Engineer and full-stack developer specializing in interactive 3D product configurators for e-commerce — 13+ years in 3D visualization and 5+ years building web-based configurators with Three.js, WebGL, and platforms like Zakeke and KickFlip. I help businesses turn made-to-order or customizable products into smooth, confident buying experiences online — whether that means a custom configurator built from scratch or a fast setup on a third-party platform. WHAT I DELIVER ▸ Custom 3D configurators — Three.js, React Three Fiber, Verge3D, WebGL ▸ Third-party configurator setup & customization — Zakeke, KickFlip, Angle3D, Emersya ▸ 3D modeling & web optimization — Blender, GLB/glTF, Draco compression, baked textures ▸ Full integration — Shopify, WooCommerce/WordPress, or any custom website ▸ End-to-end ownership — from product spec to live deployment TECH STACK React • Three.js / React Three Fiber • Verge3D • WebGL • Blender • Spring Boot • JavaScript/TypeScript • Liquid (Shopify) • PHP (WooCommerce plugins) WHY CLIENTS HIRE ME My mechanical engineering background means I understand your product before I touch a model — dependent-option logic, dimensional constraints, and manufacturing realities don't get lost between brief and build. Combined with deep 3D and web experience, this translates into fewer revision rounds and a configurator that actually reflects how your product works. I operate under the Studio Rasa LL brand and work full-time freelance. Recent projects include custom configurator platforms for furniture, industrial equipment, and made-to-order goods — live demos available on request. Ready to start when you are. Let's discuss your project.
