Building the metaverse. Led the development of the centralized audio platform on the Orion AR glasses. https://about.fb.com/news/2024/09/introducing-orion-our-first-true-augmented-reality-glasses/amp/

Alexa Automotive Team - Leading a team of six on two projects designed to improve the flexibility and ease of integrating our software into customer’s systems. ● Designed and implemented DDL, a meta-language which compiles into a modular structured data set, which can then be fed into arbitrary templates, such as HTML documentation, C++ serializing classes, etc. Alexa Local Voice Control Team- Led a team of five to deliver the “Hybrid Proxy”, an augmentation on top of the open source Alexa Device SDK. It enables a synchronized and simultaneous communication to both Alexa Cloud and the Alexa Local Voice Control (an offline version of Alexa).

Client Cocos engine team- Collaborated with other senior engineers to rewrite the existing game client using the Cocos2d engine. Client was successfully rolled out on Windows, Mac, Android, iPhone, and HTML5.- Heavily modified vanilla open source Cocos engine in order to support features like multiple windows, dynamic font step-resizing, custom class loading, and a generalized UI algorithm.

Frostbite Animation & Cinematics Team Frostbite is the game engine powering games like Battlefield 1, Star Wars Battlefront, the newest FIFA games, and many other products.- As a senior member of the prototyping team, planned the 5-year engineering roadmap to merge two AAA game engines - each several million lines of code - while minimizing any negative impact on teams that are reliant on them.- Optimized character creation workflows and created the vision of its most ideal implementation, with a multi-year roadmap to get there

Dead Rising 3 - Zombie Team (​http://en.wikipedia.org/wiki/Dead_Rising_3​) - Collaborated with a team of 200 to develop a custom game engine with Havok physics integration. - Implemented half of the zombie AI and combat subsystems. These systems were multithreaded and highly optimized to simulate over 7000 zombies at the same time. - Owned the design and implementation of the ragdoll subsystem. Delivered a system which supported powered ragdolls, constrained ragdolls, dismemberment, recovery from prone state or partial penetration, and a custom build pipeline to ingest ragdoll metadata (such as the skeleton). - Designed and developed the zombie car-clinging combat system. The system was novel in how it married physics and gameplay together in a way that wasn’t really done in the AAA space at the time. - Implemented several procedural animation systems, such as head tracking, for zombies (which unfortunately had to be cut for optimization reasons).

Tools- Implemented profiling tool able to remotely access any games compiled with it. In addition to profiling, the tool is also able to pause and step through individual frames, as well as show metrics. Kinect Fun Labs games: Googly Eyes and Kinect Me - Integrated Kinect 3D object capture and digitization, developed by Microsoft’s Good Science team. - Implemented game flow, scene director, and UI. Unreleased Microsoft Project (cancelled in mid 2008) - Programmed the animation system, NPC dancer AI, visual feedback, camera director, and object interaction in C++ and Unreal Script for a yet-to-be-announced project funded by Microsoft. 20,000 Leaks (​http://en.wikipedia.org/wiki/Kinect_Adventures​) - Microsoft first party title bundled together with the Kinect. - Implemented the Gameplay Systems and animation code support using C++ and Unreal Script. Exoriare (​http://arg.exoriare.com/​) - Programmed and co-designed Global Forager, the main Flash game experience on the website. - Developed the back end server system with customized forums. At its peak, there were about 6000 concurrent users

Shipped products: NBA 08 PS2/PC, NHL 08 PS2/PC, Rugby 08 PS2/PC, Euro 08 PS2/PSP/PC, NBA 09 Wii/PS2/PSP, NHL 09 PS2/PC. Wii Prototype - Designed and programmed a game prototype for the Nintendo Wii. - A key feature in the prototype was the 1-2 frame response time from Wiimote “waggle” to game
