Experience

SpaceX

Redmond, WA

Senior Software Engineer

2018 – 2021

• Starlink

  • Worked on flight software running on Starlink satellites as well as ground systems.
  • Squad lead of bus software team for half a year. In charge of planning, prioritization, and resolving issues across teams.
  • Brought up new power, battery charging hardware, and new Ka RF systems running across microcontrollers and SoC’s. Worked with multi-disciplinary hardware teams to quickly bring up hardware for validation and on-orbit testing.
  • Implemented GNC (Guidance Navigation Control) algorithms on satellites with GNC team.
  • Owner of the telemetry system for satellites. Implemented tools to budget and reduce our date rates as our system scaled up, and led the design for a new telemetry system to be more reliable and compact.

Microsoft

Redmond, WA

Senior Software Engineer

2015 – 2018

• HoloLens / Windows Mixed Reality

  • Worked on head tracking technology for HoloLens. Implemented infrastructure for ground truth testing. Performance optimizations for tracking code.
  • Profiled and implemented optimized x86 SIMD code for core tracking algorithms. Resulted in top bottlenecks running multiple times faster, allowing us to ship mixed reality on low-power devices.
  • Worked on first party application development for HoloLens. Benchmarked performance and implemented solutions to make sure experiences run in a smooth 60fps frame rate. Prototyped novel UX experiences for mixed reality.

Electronic Arts – Maxis

Emeryville, CA

Software Engineer / Senior Software Engineer

2007 – 2015

• Unannounced Project

  2014 – 2015

  • Lead of graphics team composing of 5 graphics software engineers.
  • Provides technical leadership for the core engine and graphics features, and served as point person for different core systems.
  • Helped prioritized features and set goals for the team. Reviewed tech designs for graphics, gameplay, and tool features.

• SimCity / SimCity: Cities of Tomorrow

  2009 – 2013

  • Worked on Mac/OpenGL port of the game. Performed OpenGL optimizations and ported our DirectX-specific command buffer multithreaded renderer to OpenGL which accounted for up to 30%-40% performance improvements.
  • Implemented the graphics system for curved roads, a major feature in the new version of SimCity. Work involved a custom extrusion system for efficiently creating mesh based on curved cubic splines, and a data- driven component-based method of authoring roads allowing for quick iterations and managing multiple types of roads and different combinations of intersections from them.
  • Worked on terrain flattening system which allowed roads and lots to dynamically flatten the terrain geometry underneath them to create a tight fit no matter how far the camera is zoomed in or out.
  • Built the HTML/JavaScript UI system “SCRUI” used by the game. Worked on both the core library and the WYSISYG editor that allowed artists to easily create new UI layouts and behavior-driven key frame animations inside a browser.
  • Integrated WebKit to be able to host the HTML/JS in game. Implemented efficient ways of bridging C++ and JavaScript, optimizing rendering and JavaScript performance, and reducing memory cost of managed code.

• Spore / Spore: Galactic Adventures

  2007 – 2009

  • Implemented in-game pollination, allowing players to share and download content such as creatures, vehicles, buildings, and adventures with other players. Also worked on “Sporepedia”, a centralized in-game browser for content created and shared by other players.
  • Improved UI performance by implementing image atlas pipeline.
  • Implemented dynamic mesh generation for roads on a planet.

Electronic Arts

Redwood Shores, CA

Software Engineer Intern

06/2006 – 08/2006

• • Implemented real-time displacement mapping on Xbox 360 for The Lord of the Rings: The White Council.
