I am in need of an experienced freelancer proficient in Kotlin and Jetpack Compose coding to assist with the development of our 'Mridanga' app. The tasks at hand involve fixing tempo control, adding Firestore support for multiple audio, and Jetpack Compose UI enhancements for audio features and playback. I have asked for assistance in these areas as I am confident they require specialist knowledge and expertise. I'm open to any effective methods that the freelancer deems appropriate, but I understand the importance of a structured timeline in delivering such projects; I'm requesting a moderate completion window of 3-7 days. I'm looking for someone with solidarity of experience in handling such programming tasks. It is also essential they are considerate towards the rotation of the audio files, providing an intuitive tempo adjustment system that allows for time manipulation of the sound files. Furthermore, they should be able to create an efficient user interface through the Jetpack Compose framework. If you believe you are the one to take on this project, please don't hesitate to contact me. I look forward to working with you.
