Three apps.
Built from zero.

Production Firebase web apps — vanilla JavaScript, real-time Firestore sync, and automated CI/CD pipelines. No frameworks, no build steps.

◆ TODO List

Session-Start Firestore Backups
At the start of every Cowork session, Claude reads each project's last_backup.txt. If it's 7+ days old (or missing), backup_firestore.py runs automatically and saves a timestamped JSON export to the local backups/ folder. No launchd, no cron — triggered by the session itself.
