Core interactions
Built Guestlist Pro to keep track of attendees for intimate events without relying on cloud services.
Everything runs in the browser, persists locally, and syncs changes instantly so teams can collaborate around the same device.
Challenge
Needed a zero-dependency tool that worked offline and kept guest data organized during fast-moving events.
Approach
Implemented a lean state manager in vanilla JavaScript, layered on search and filtering, and stored data in localStorage for resilience.
Outcome
Made it possible to stand up a polished guest management flow in minutes, even without Wi-Fi.

- Instant search, sort, and filtering
- Local persistence for offline scenarios
- CSV export/import for quick backups
