About me
I'm a versatile 3D artist who transforms flawed, unfinished, or purely conceptual work into polished, production-ready results. From fixing corrupted STL files and refining raw scan data to sculpting original models and delivering hand-painted physical pieces, I handle the entire 3D workflow. Using Blender, ZBrush, and Meshmixer, I approach every project with the same level of care and precision, no matter the scope. Expect solid geometry, straightforward communication, and deliverables that genuinely perform.
Let's make it happen!
