HQ
A self-hosted agentic life manager — installable PWA with push, live sync and a cron scheduler that works while you don't.
The product
HQ is a headquarters for your day: time slots, todos, goals and reminders in an installable PWA that pushes notifications to both phone and desktop, stays in lockstep across devices over WebSockets, and shares straight into your scratchpad from Android's share sheet.
It's also an exercise in owning the whole stack: a zero-framework frontend with a custom store and router, a hand-rolled AWS SigV4 signer for R2, a versioned SQLite migration runner, and a per-minute cron scheduler with timezone-aware reminder evaluation.
