Android Pinoy Calendar Keyboard app

I'm looking for an experienced Android developer to create a unique Pinoy Calendar Keyboard app. The main features that I want this app to have are as follows:

- **Philippine Holidays Highlight:** The app should be able to highlight the holidays that are celebrated in the Philippines.
- **Reminder for Upcoming Holidays:** The app needs to send reminders for the upcoming holidays. This feature is crucial to the app as it will help users to remember and prepare for the upcoming holidays.

The ideal candidate for this job should have experience in Android app development, with a strong understanding of creating keyboard apps. They should also have experience in integrating calendar functions and setting up reminders within an app. Knowledge of the Filipino language and culture would be advantageous.

I'm open to any recommendations on how to improve the app or additional features that might enhance its usability. Please provide examples of your previous work and how they align with the requirements of this project.
