AI Engineer • Former Particle Physicist ⚛️ • Former Risk Modeler 📈
I've spent my whole career looking inside systems that would rather stay opaque — first particle collisions, then risk models, now neural networks.
The models talk to us all day. I want to be able to affect them back.
Why I'm really doing this → the manifesto
My personal site is a chat with a tiny LLM running entirely in your browser, and every answer it generates renders as a real particle collision. Click the event below to fire your own question into the chamber:
The stack that makes a model legible in production — from watching, to diagnosing, to fixing. Watch it think (brainscope) → diagnose why it did that (causal replay + the lens) → fix it at the source with a calibrated steering vector, receipts attached (hidden-directions → hotwire-vllm). Observability first; intervention last, once the instruments have earned it.
Tip
Don't read — just do it. The core of the lab is on PyPI:
pip install hidden-directions brainscope hotwire-vllm
— the vector factory, the live lens server, the production vLLM plugin. CPU is fine:
brainscope --model tiny— a browser view of a model thinking- point your own OpenAI client at brainscope — watch your app's live traffic
No account, no course — install and look.

- 🌙 tri-kumpani — Li Po's Drinking Alone under the Moon, read by a small Chinese model twelve hundred years later: tap a token to see which words it raises its cup to, head by head, then pour it wine and watch the next verse fall apart into Chinese characters. The tokenized poem is also printed on a jacket. ▶ open it
