Led a team of mechanical engineers delivering custom optical sensors across the Apple portfolio, enabling features such as Face ID, proximity sensing in iPhone and AirPods, and the digital crown in Apple Watch. Provided leadership across new tech incubation, module architecture, and design implementation including vendor selection, factory bringup, validation plans, FA, and ramp.

Mechanical design lead for Face ID flood illuminator, ToF proximity sensors, and Touch ID modules for iOS and Mac including fingerprint and force sensors. Detailed design of semiconductor devices, micro-optics, sealed enclosures with advanced materials and failsafe mechanisms, system integration schemes, and test equipment to emulate in-field stresses and accelerate iteration. Introduced 4 new technologies across 18 modules, delivered into >30 Apple products, with >500 million shipped.
