Hire the Best OpenGL Developers

I’m a 3D Artist with a strong foundation in game-ready assets, specializing in realistic hard-surface modeling for games and film. My workflow includes optimized topology, PBR texturing, UV mapping with texel density consistency, LOD creation, and biped character rigging. I also integrate assets into Unreal Engine with production constraints and real-time performance in mind. In addition, I run my own Unreal Engine-focused game development studio. If you’re looking for support in any of these areas, I’d be happy to collaborate and help bring your project to life.

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.
