A little context

Hello, I'm Sean.

Founder of Arkah and Bluprnt.

I build software for thinking through ideas. Arkah turns hard questions into structured research reports. Bluprnt is an outliner where every bullet can grow.

This site is my notebook for the engineering work around those products. The writing follows specific decisions: a library that behaved unexpectedly, a constraint that helped, a detour that took longer than it should have.

Some of that work also becomes open source. You'll find schema tooling, agent guardrails, and integrations in Arkah's open source projects.
