Technical HCI Research Assistant:

UBC X-Lab, co-authored two papers on AR/VR telepresence. Developed real-time ML tracking pipeline using Gaussian Splatting for AR/VR telepresence with PyTorch, CUDA, and OpenCV, achieving <1s physical-to-virtual object synchronization. Implemented multi-threaded 360° streaming system in C++ with IPv6 multicast, reducing latency by 79% and bandwidth by 94%.

Computer Networking Teaching Assistant:

UBC CPSC 317, designed tutorials on network fundamentals (TCP/UDP, IP, TLS) with example C code. Taught security and cryptography with demonstrations of attack vectors. Provided debugging support to 50+ students for DNS, SMTP, and STCP assignments.

C# Unity Developer Intern:

VictoryXR, designed avatar customization system with compositing shaders adding 30+ options. Doubled multiplayer capacity from 50 to 100+ users by reducing memory usage 40%. Integrated Inverse Kinematics for realistic full-body avatar movements in VR environments.

Debate Coach:

Fostering Debate Talent (FDT), coaching students 1-on-1 and in classes of 15-20 to form persuasive arguments in competitive debate.
