I design things that get hot, spin fast, or get inserted into people — _
Mechanical engineer working across thermal systems, HVAC design, and precision manufacturing. I run a surgical instrument company on the side, mostly because stopping felt lazy.

A gearbox is a negotiation. Trade torque for speed and watch the numbers argue — the same tradeoff that set Pulsera's gear ratio.

Thermal
Cold plates, heating loads, and heat that refuses to stay put.
Mechanisms
Drivetrains, tolerance stack-ups, and things that must not rattle.
Manufacturing
GD&T, DFM/DFA, and QC that catches it before the customer does.
