What I'm working on

Project What it is Code
🔊 On-device voice for clinical software
Medical Informatics Engineering · summer 2026		 Wake word, speaker verification, and Whisper dictation running fully in-browser through ONNX Runtime and WebAssembly. Patient audio never leaves the device, under 250ms end to end. mieweb/ui
🎬 LLM editing agent
Medical Informatics Engineering · summer 2026		 Emits validated, auditable edit operations against an immutable transcript snapshot instead of free text. Shipped with health-checked auto-rollback CI. mieweb/ui · pulsevault
🚦 LiDAR traffic safety pipeline
JHU smart intersection project · ongoing		 Turns BlueCity and Ouster sensor feeds into automated safety reports, with a validation layer that rejects any LLM finding not backed by the underlying records. A full day of manual reporting now takes about 90 seconds. private
🎙️ Speech and retrieval infrastructure
LaunchStack · Jan to May 2026		 Speech-to-text pipeline with two interchangeable backends, plus document ingestion over a PostgreSQL and pgvector retrieval layer. private
⚽ Expected Possession Value
JHU Sports Analytics · fall 2024 to May 2026		 Recursively values every shot, pass, and dribble decision from MLS tracking data, personalized per player. private
🏆 World Cup predictor
Independent		 Calibrated model ensemble over 62 engineered features, with a Monte Carlo simulation of the real 2026 bracket. Test log loss 0.827. WorldCupPredictor
🏥 AI for Surgery Lab
JHU · incoming fall 2026		 ML that assesses operative technique from surgical video and motion data. starting
