- Gorush integration for push notifications
- Redis for caching and job queues

Features implemented:

- Residence management (CRUD, sharing, share codes)
- Task management (CRUD, kanban board, completions)
- Contractor management (CRUD, specialties)
- Document management (CRUD, warranties)
- Notifications (preferences, push notifications)
- Subscription management (tiers, limits)

Infrastructure:
- Docker Compose for local development
- Database migrations and seed data
- Admin panel for data management
