I'm a Machine Learning Engineer at Nurix.AI, building speech and multilingual RAG systems. Before that — deep-learning research, an AI role in Tokyo, and leading autonomy on a student Mars rover.

Projects
Selected work
A few things I've built across ML, robotics, and backend systems — from research to production.
Speech Emotion Recognition
ReleasedA multi-corpus emotion-recognition model in PyTorch — trained on IEMOCAP, RAVDESS, and CREMA-D — reaching 87% classification accuracy. Built at Nurix.AI.
Multimodal Multilingual RAG
BuildingA retrieval-augmented generation pipeline serving multiple languages and modalities at 96% accuracy with a p95 latency of 2.93s. Built at Nurix.AI.
Distributed Deployment Platform
ReleasedDeploys GitHub repos to the web via AWS S3 + ECS, with a Node.js API and reverse proxy, a Kafka log pipeline, and PostgreSQL for real-time build logs.

Paper notes
Summaries of papers I'm reading — mostly ML, retrieval, and systems. A living, cross-linked second brain, written to be re-read.
