Overview
A local-first extension that runs on the browser session alone, with no backend or login. It snapshots and compares audience state like git and analyzes engagement, and all data stays on the device. Write actions are off by default, opt-in, and conservatively rate-limited.
My Work
- ▸Local-first architecture with wxt (MV3) + TypeScript + React + IndexedDB
- ▸Resumable collection (cursor persistence) stays memory-safe at scale
- ▸vitest tests + inherits the governance harness
Highlights
- Git-like snapshots/diffs to track audience changes
- Local-first — no backend or login, data never leaves the device
- Engagement analytics + safe pacing (opt-in, rate-limited)
