Engineering notes
Performance
What keeps it fast
- Admin dashboard built for quick status scanning across all active reservations
Challenges
What was hard to get right
- Handling payment webhook edge cases (delayed, failed, or duplicate callbacks)
- Preventing race conditions when two guests book the same room simultaneously
Lessons learned
What I'd carry into the next project
- Payment status should always be driven by the provider's webhook, never assumed client-side
