Your guide to fewer parts, lower cost, and simpler assembly.

First-principles mechanical design from a former Tesla Mechanical Design Engineer.

About

I help teams turn concepts into manufacturable, cost-effective products, with fewer parts, easier assembly, and a faster path to volume production. 20+ years of mechanical design across batteries, power electronics, and data center cooling, including senior roles at Tesla (battery cell manufacturing equipment for Tesla’s 4680 cells, and mechanical design for the Dojo AI supercomputer) and APC by Schneider Electric (the EcoFlair data center air economizer and the EcoBreeze modular cooling line).

Proof points

• ~80% smaller footprint for Tesla’s 4680 battery cell formation equipment

• $90M per phase 4680 battery formation lines supported, Texas & Berlin (Tesla)

• 35% cost reduction on plumbing, sheet metal & weldments on the EcoBreeze unit (APC by Schneider Electric)

• U.S. Patent 10228196B2: large-scale modular indirect evaporative heat exchanger for data center cooling (APC by Schneider Electric)

• Tesla Dojo — mechanical design of the super-dense power supply for Tesla’s Dojo AI supercomputer cabinet

Tesla AI Day: the Dojo cabinet, featuring my power supply design.

Tesla Battery Day: my mechanical/electronic design and layout set the base footprint of 4680 formation equipment, which Tesla says cut its formation factory footprint by 75%.
