Lead System Engineer on an AR Device. Responsibilities include:- Defining, managing, and validating system requirements spanning AR displays, computer vision sensors and algorithms, custom silicon, wireless, compliance, fitment, and product/industrial design- Driving executive level reviews for key technical product decisions- Leading prototyping and development of requirements for new technology introduction (NTI)- Defining HW build requirements, partnering with MTE, DVE, and Reliability teams to achieve build goals- Working with CV / ML / SW teams to drive E2E validation and feedback into product- Partnering with Product Management to define use cases and translate to engineering requirements- Providing subject matter expertise in Display Technology, Calibration, VIO, Mapping, Reconstruction, and World Locked Rendering for AR devices

I currently work on 3D Mapping at Facebook, making the publicly shared LiveMaps vision a reality. Come join us, we're hiring!

I was an early member of the HoloLens team and led a broad range of engineering projects spanning the gap between AR HW and computer vision SW from research dream to shipping product. I grew our calibration team from research code to a platform supporting multiple products (HoloLens, Windows Mixed Reality, Azure Kinect) and was active in product design and architecture.Factory Calibration: As the de-facto architect of our factory calibration systems for 6 years, I designed, prototyped and deployed fully automated SLAM (Cameras + IMUs), Display, Eye Tracking, and Depth calibration and test equipment for HoloLens v1, v2, and Windows Mixed Reality HMDs. I designed parts, wrote code, managed a team of CV experts, partnered with 1st and 3rd party manufacturing teams, and regularly traveled to factories to oversee line bringup and ops.Online Calibration: I drove design, development, data collection and validation efforts for SLAM re-calibration algorithms which shipped on all HoloLens and Mixed Reality devices. I developed a new sensor for active alignment of stereo displays and drove HW prototyping and software development of the final system which shipped on HoloLens 2. HoloLens Architecture: I initiated a thermal and structural rigidity workstreams between HW and CV teams. I introduced the use of calibration tools for reliability testing on AR devices to map changes in HW to algorithm performance and experience degradation. I championed World Lock Quality and drove R&D of calibration and control mechanisms for MEMS displays to ensure user comfort.Prototype Development: I played a key role in bringup of computer vision stacks on a wide range of prototypes from pre-HoloLens HMDs to experimental MEMS display projectors. I designed HW tests and coordinated end-to-end validation of algorithm performance on HW, feeding back learnings to product teams.Contributor on several patents for online calibration, active display alignment, and sensing mechanisms.

I was honored to serve as a Course Assistant for Stanford’s infamous computer systems class, CS107, teaching memory management, data representation, compilers, assembly and more. As most student’s first introduction to low level systems, it was a great opportunity to grow as a leader and mentor through code review, programming labs, and office hours.Key Proficiencies: Programming and Compiling (C,C++,gcc), Debugging (gdb), Memory Management (valgrind), Assembly (x86)

I worked with a small team of volunteer engineers to maintain and update the radio station’s systems, from building and provisioning a small server room to architecting, planning, and executing a transformative shift from analog to digital mixing equipment. I also hosted a weekly live radio show and served as a sound technician for live music performances and talk shows on air.Key Proficiencies: Audio Engineering, Networking and Electrical Wiring

Practical experience in the end-to-end injection-molded parts design process, from concept to detailed design, FEA, static and moldflow analysis, and lab testing on prototype parts. Worked almost entirely in Japanese for 3 months. Patent filed for final designKey Proficiencies: Solidworks, Ansys, FEA, Stress and Reliability Testing

Broad range of professional engineering experience. Designed components for unmanned helicopter with consideration of manufacturability, procurement and environmentalfactors (coatings). Learned pareto analysis techniques to identify and address key hardware issues, and ran an Engineering Review Board for change management on an active US Navy unmanned vehicle project. Key Proficiencies: CATIA, Pro E and PLM.
