Built a precision flexure for a piezo actuator giving the exposure system accurate motion across a 200 µm range — small piece, but the whole exposure precision depended on it. Delivered a flexure-based XYZ stage hitting 180 Hz first-mode at 20 kg system weight, covering 100 µm to 2 mm of travel. Cut weight on several structural parts using 3D-printed tetrahedral lattices — material only where it's doing structural work. Pushed first-mode above 200 Hz on overhanging assemblies through targeted cantilever designs, cutting tip deflection. Started an LED test fixture as a quick intensity-measuring rig; it ended up scaled into a mass-production qualification tool.
