I am a system engineering lead for handheld devices and special projects at Apple. I have R&D interest and experience in: - battery powered embedded platforms - compact, low distortion audio integration - predictive numerical models - integration of compact MEMS devices - DC/DC power conversion - circuit model / extraction techniques (Ansoft, Sigrity, HSpice, LTSpice) - extraction for signal integrity models - RF / desense techniques - design for mass production (N*1M scale), statistical analysis - DFM considerations for flexible printed circuits - noise and vibration effects / mitigation techniques for SMT components - rapid prototypes - field programmable gate arrays Past projects include: - Apple Watch 1 - iPod (touch, 5th gen) - iPhone (4s, 5c) - iPad Pro (early demos, architecture)

System Lead EE @ Development, design, simulation, and manufacture of major internal hardware components for Apple Watch 1. From October 2013 to July 2014 (10 months) Device Hardware EE @ Device hardware engineering, concept, design, fabrication, validation, manufacture, and mass production ramp. From June 2012 to October 2013 (1 year 5 months) Device Hardware EE Intern @ Device hardware engineering, concept, design, fabrication, validation, manufacture, and mass production ramp. From January 2011 to August 2011 (8 months) Lead Engineer @ Concept, development, and roll-out of interactive theme park ride and product for Walt Disney Imagineering ImagiNations design competition. Design involved multi-disciplinary work with graphic design, architecture, and UX design. Developed hardware for gesture recognition / interaction outside of ride. Used wireless Zigbee transponders and onboard sensors to demonstrate immersive experience in a custom hardware solution. Developed and demonstrated signal processing algorithm for multiple cameras for gesture recognition of guests. From January 2009 to June 2011 (2 years 6 months) Hardware Engineer @ System X Enterprise series hardware engineering co-op Designed and deployed FPGA VHDL for onboard 'glue' logic for device restarts, power cycling, and firmware updates. Server architecture. From January 2010 to December 2010 (1 year)
