The Brain
A full-stack personal operating system — a self-hosted app that pairs a private note/knowledge base with the Anthropic SDK to run day-to-day planning and decision-making.

The problem
Most productivity tools are either a dumb notes app or a generic AI chat window with no memory of anything specific to how I actually work. Neither one holds enough context to be genuinely useful day to day.
What I built
A full-stack personal operating system: a React + Vite frontend, an Express + SQLite backend, and the Anthropic SDK wired in as the reasoning layer, self-hosted and kept running via PM2. It uses a personal knowledge base as its long-term memory, so it can reason about ongoing projects and decisions with real context instead of starting from a blank page every time.
Why it matters
It's the same build pattern behind every project on this site: find the actual bottleneck, scope a specific fix, direct AI to build it, and keep iterating against how it's really used — just pointed at my own workflow instead of a team's.
Status
Actively developed and used daily — this is a living system, not a finished product.
