THE WORK BEHIND THE PROFILE

Proof of Work

Deep Speech: Scaling up End-to-End Speech Recognition

First author of the landmark Baidu Deep Speech paper, proving that replacing complex phonetic acoustic pipelines with a single recurrent neural network trained end-to-end with CTC achieves state-of-the-art accuracy in noisy real-world speech.

Scope & limitations

End-to-end recurrent models without attention mechanisms struggle to maintain alignment over multi-minute audio streams.

Context: Bidirectional RNNs, CTC loss, custom GPU parallel prefix beam search decoders.

MLX: An Efficient Machine Learning Framework for Apple Silicon

Conceived, engineered, and open-sourced MLX, a NumPy-like array framework with composable function transformations (grad, vmap) that exploits Apple Silicon's unified memory architecture for zero-copy CPU/GPU execution.

Scope & limitations

Exclusively optimized for Apple Silicon hardware; non-macOS platforms are not natively accelerated.

Context: Apple Silicon Metal, unified memory up to 192GB, C++ core with Python bindings.
