​Performance Optimization

• Led platform-wide performance strategy to ensure optimal experiences for both show creators and show attendees:

  • We achieved a baseline performance of 72 FPS in Mobile VR with dynamic lighting, multiple fully featured characters, time synced visual effects, and post processing.

  • Maintained 60FPS for PC show controllers, while supporting major fidelity boosts, like SSS on characters, Lumen GI, and more.

  • Advocated analysis-driven optimizations, to correct default assumption that we were always GPU bound on Mobile VR hardware.

  • Leveraged many tools including Unreal Insights to diagnose CPU issues and validate gains with real data.

• Reduced character animation CPU costs by on average 50% on device:

  • Shifted modular avatar logic from Blueprints and Tick over to C++ where possible.

  • Refactored our Animation Blueprints to use thread safe runtime updates.

  • Converted our runtime color modification of avatars from constant polling to event-driven updates.

​

Feature Development

• Served as the Product Owner to our show creation tools:

  • Transformed our approach to building shows, which improved velocity from taking weeks or months to build a show, down to a matter of minutes- using robust library access and live configuration of shows on the fly.

  • Maintained roadmap of future improvements to the tools through continuous course correction and team feedback

• Built core show systems we used, from prototype to production:

  • A modular performer avatar framework that enabled rapid configuration by our character team

  • A user movement driven VFX system emitting particles from attendee skeletal meshes, with cross-user intractability

​​

Mentorship

• Onboarded and guided Artists and other Technical Artists, introducing them to our many tools and complex tech stack​

• Served as direct report for several TAs throughout the project, as both a team lead and on a personal 1:1 level
