We need a flutter + firebase developer for app customization

I am looking for a Flutter and Firebase developer who can help me customize my gaming app. The primary purpose of the app is to provide a seamless gaming experience for users. I have a detailed list of customization requirements that need to be implemented within the next 3-4 weeks. The ideal candidate should have experience in developing gaming apps, as well as in working with Flutter and Firebase. They should be able to work independently and provide regular progress updates. Strong communication skills are also a must.
