Voice-Controlled AR Hand Assistant

Jan to May 2025

Built a multi-modal AR pipeline on Meta Quest 3 using the Meta XR SDK. Integrates YOLOv11 for real-time object detection, GPT-4o for natural language understanding, CLIP for zero-shot classification, and Moondream for visual question answering.

  • Meta Quest 3 + Meta XR SDK deployment
  • YOLOv11 real-time object detection
  • GPT-4o + CLIP + Moondream multi-modal pipeline

Transformer Language Model from First Principles

2026

A GPT written from scratch in NumPy and PyTorch without reference implementations. Along the way I measured RNN gradient decay, pre-norm versus post-norm gradient flow, and an emergent previous-token head (97% of attention mass).

  • Hand-derived backprop in NumPy, validated against numerical gradients (under 1e-4)
  • Multi-head causal attention verified numerically identical to PyTorch's fused kernel
  • Trained an 892K-parameter GPT (4 layers, 4 heads, d_model 128) on character-level Shakespeare; 54 unit tests passing
