Location-Based Reminder Mobile App Development (developer from India)

I'm seeking a proficient mobile app developer to create a Location-Based Reminder App inspired by this open-source project: https://github.com/mertcansegmen/location-based-reminder.

Key Features
- The app should primarily allow users to create reminders based on specific locations.
- Utilize the Google Maps API for a seamless mapping experience.
- The app must smoothly run in the background, without draining the device's battery.
- Store data locally with the potential for future integration with Firebase for cloud sync.

Target Platforms
- The initial build will be for Android, with iOS as a potential second phase.

Preferred Tech Stack
- Proficiency in Kotlin or Java for Android is a must.
- Experience with Jetpack Compose or XML layouts is preferred.
- Familiarity with modern Android architecture (MVVM, Room, etc.) is essential.
- Firebase knowledge is a plus for optional cloud sync.

Project Overview
- The primary function of the app is to allow users to create location-based reminders.
- Notifications should only trigger upon entering a designated area, not leaving.
- A user-friendly map interface will display all active reminders.

Ideal Candidate
- I am looking for a developer with a strong background in mobile app development, particularly with location-based apps.
- Previous experience with the Google Maps API is highly desirable.
- The ideal candidate should be able to demonstrate a portfolio of similar projects.
- Excellent communication skills and a collaborative spirit will be highly appreciated.
