About
3D Environment / Level Artist with 7+ years of commercial experience across game, VR and interactive production, including client-delivered VR experiences shown at public events and used in B2B settings. I own the full environment pipeline: asset creation, UVs, baking, PBR materials, set dressing, lighting, optimization and engine integration. Experienced with large-scale worlds, modular and reusable content, terrain, foliage, LOD systems, lightmaps and occlusion culling. Strong technical background in Unity, comfortable working solo or in distributed international teams.

Also
Kelhem YouTube channel: tutorials on Blender, Unity and modern 3D workflows.
Three years of daily work with an English-speaking client: calls, technical discussions, coordination.
