Things I've designed and built, mostly at the intersection of mechanical systems and the software that documents them.
Modeled air handling units in 3D straight from 2D engineering submittals, so coordination happened before equipment was ordered instead of during installation.
Built custom piping specs and part catalogs for refrigeration systems using our real suppliers' components. Wrong orders and guesswork went down; it became the standard on later projects.
Thirteen custom workflows and plugins that automated the repetitive parts of BIM coordination — the kind of tasks everyone hates doing by hand.
An interactive museum exhibit — a robotic arm simulating fishing scenarios — built to teach kids about sustainable fishing. Fun rating 4.64/5; servo survival rate considerably lower.
