Hi, I'm Pri 🌝

Software engineer, fourteen years in. These days I'm a bit obsessed with AI. Not the models themselves, but how to work with them: building good agents and the new kinds of apps they make possible. And, of course, how to keep AI from taking my job. 🫠

What I'm building More about me

Open source

Arcana OS

An open-source multi-agent operating system: a cast of agents, each shaped by a tarot archetype that defines its voice and behavior, and a meta-agent that sees it all, handling memory, tools, identity, and guardrails so your agents don't have to. Local-first, and works with local or hosted models.

Closed beta

Roamie

A proactive AI travel companion, currently in closed beta. An agent that helps you navigate travel logistics with tips and warnings, and keeps an eye on important changes while you stay present. The code is private, but I'm always happy to talk about it.

By day

By day I'm a senior backend engineer at Lunit, building the oncology data platform and the slide annotation system that produces training data for our cancer-detection models. Pathology data turned out to be way more interesting than I expected.
