Festival Reminder Mobile App

I'm looking for a skilled mobile app developer to create a festival reminder app for both iOS and Android platforms. The app should support multiple languages and include the following key features:

- Calendar Integration: Sync with users' calendars to keep track of festival dates.
- Notification Alerts: Send reminders and alerts about upcoming festivals.
- Festival Information and Details: Provide comprehensive information about each festival.

Ideal candidates should have experience in mobile app development, multilingual support, and a strong understanding of calendar and notification functionalities.
