AI systems
LLM classification and evaluation, semantic search, and AI built into everyday workflows.
Example: AI vs. human sentiment analysis
Research software engineer and AI consultant
Together, we’ll achieve your vision.
AI systems, search, websites, and mobile apps for researchers, startups, and the teams around them. I translate your idea and expertise into software that works. You get demos of your idea until we’re aligned.
Also open to the right full-time role.

What I build
From first demo to working system
Search over your data
Fast, precise search over specialized collections, by keywords or by semantic meaning.
Examples: Melody Search Index, FMC Research Assistant
Websites and mobile apps
Full-stack apps, from the first clickable demo to the shipped product.
Example: Yellowstone field guide
Data and automation
Pipelines, computer vision, and signal processing that take the slow, manual parts out of the work.
Examples: Auto-cropper, Biosignal research

Melody Search Index
- Challenge
- Researchers waited overnight for the index to rebuild and minutes for every search.
- What I built
- A full-stack melody-similarity search on Elasticsearch, replacing sliding-window n-gram matching, plus OCR and RAG over 10k+ records.
- Result
- Indexing in minutes and searches in seconds, used by researchers worldwide and presented in Texas, Salzburg, and Venice.
Search · Live FMC Research Assistant Search over 4,033 documents of 19th-century French music press, by keywords or by semantic meaning, with reranking, running entirely on local GPUs. LLM evaluation · Talk, Dec 2026 AI vs. human sentiment analysis An LLM pipeline that codes newspaper coverage the way trained research assistants do, and measures how closely it matches them. Mobile · In progress Yellowstone field guide app An offline Android field guide, built from a 40-page microbiology guidebook, that tells you what's alive in the water you're standing over.
