Im a Tech Artist working with Maya extensively (and lately a fair bit of houdini).
Primarily a rigger/character guy, but I dabble in some effects as the need arises (especially as it relates to characters) and at times operate as a maya-generalist within our somewhat small CG team.
Ive spent a fair few years as a pipeline developer as well, usually with a focus on layout, animation and assets department workflows.
I’d say I have expert-level knowledge of Maya, including all tools,nodes and APIs, and maybe intermediate (or lower) level knowledge of houdini. Very handy with python - and if you really force me Ill pull some c++ out too, but its rusty and wasnt strong at its most rust-free.
