Hire the Best Game Developers
in Switzerland

MS CS & For 10 years the best threejs developer on upwork. Working from the webgl fundamentals, all the way to R3F, webgpu and BabylonJS. Why I do three.js? During my master in CS I realized the future was 3d graphics for the web. I do GIS, CAD, data visualizations, ecommerce, landing pages and more. For custemers like American Express, Coca Cola, The Champion League and more. Recently a lot of people vibe coding with claude asked me for help to improve their code. Are you stuck with threejs? Get a proper WebGL engineer like me. Need more support? I can develop, optimise, design and put into production complex systems and applications. Specialised in three.js, React, and JavaScript. People also hire me because I'm fast and I don't get stuck in technical limitations. I specialised in getting into complex projects that were already running and fixing them quickly. Trusted by The World Bank, American Express, Siemens, MIT & PerkinsWill. I also like to discuss WebGPU, WebXR and VR. 🌟 Good to know ‣Degree in Computer Science with distinctions (top 1%), -Master's in CS and MBA candidate at UvA, Amsterdam ‣Co-founder at ohzi .io ‣Education in fine arts, design and architecture ‣Living in🇪🇺, ex🇦🇷🇺🇸🇨🇭🇦🇩🇬🇧🇹🇼🇨🇳 ‣Working remotely for ten years; +15 years with CAD tools, Data Visualization & GIS application ‣Excited about the latest web developments (WebGPU, Metaverse, XR, AI, WebGPU) ‣100% job success ‣75+ WebGL projects delivered in Upwork and many more outside ‣3000+ hours tracked ‣Happy to get into calls Here's what I bring to the table: △ Experience: I've released and maintained hundreds of WebGL/WebGPU/WebXR and Three.js/Babylon.js applications over the past decade.
