Building tools for power hardware R&D!

Working closely with system framework and 3D rendering engineers, I helped stand up a system of automated testing for complex applications, services, and libraries on Oculus Quest devices that increased their stability and reliability.

• Introduced automated instrumentation testing to a VR virtual presence platform on Oculus Quest devices.

• Engineered workflows for running instrumented tests in continuous integration on both C++ and Kotlin/Java framework components.

• Improved performance and reliability of testbed applications via coroutines in Kotlin and C++.

• Designed testbed application UX to match developer user specifications.

• Automated end to end testing of VR apps using Jetpack Compose UI interaction and device state for validation.

• Helped increase organization-wide unit test code coverage by an order of magnitude.

Enhanced Video Conferencing User Experience and stability of the BlueJeans Android application. Integrated visual effects into video streams using C++ multimedia and computer vision library.

• Implemented UI and data state improvements for TeleHealth sessions which increased data transfer reliability as well as the breadth of health data sources that users can share with doctors through the platform.

• Designed layouts for virtual background controls using JetPack Compose creating a stylish and performant UX.

• Integrated virtual background VFX generated by C++ computer vision and multimedia rendering libraries into meeting video streams allowing users to create immersive, branded, or privacy focused conference spaces.

Advanced Verizon XR’s AR/VR platform engine, SDK, and applications. Developed numerous immersive games and experiences to delight and empower customers.

• Developed procedurally generated graphics effects for an AR game using our C++ API for material and shader code generation together with OpenGL APIs for optimized rendering, producing an exciting immersive effect that can be portable across platforms and shader languages.

• Integrated high performance AR/VR networked asset loading code into the mainline engine, reducing asset load times from minutes to milliseconds.

• Authored a whitepaper on procedurally generating a ribbon trail graphical effect attached to two bones of a skeletal animation armature to document R&D knowledge and explore the theory behind the application.

Developed, tested, and validated Android system services across three OS version upgrades and dozens of device models. Analyzed and debugged low level telecommunications firmware behavior.

• Lead engineer analyzing and resolving Qualcomm/Samsung embedded C/C++ firmware bugs in the on-board diagnostic module for Verizon system images, resolving diagnostic reporting bugs for multiple high profile device models with millions of active users.

• Debugged Qualcomm C modem code and Samsung modem drivers to help isolate causal factors in diagnostic reporting issues such that accurate network KPIs could be monitored on test devices, helping Samsung and cellular carriers produce and tune higher fidelity phones.

• Developed diagnostic system service components in C++ based on the GSMA's cross-chip modem diagnostic standard MDMI to measure cell signal KPIs regardless of underlying hardware.
