AI-Powered Task Manager App

I'm looking for an experienced developer to create a mobile app for both iOS and Android platforms. The app's primary function is to process audio input (MP3 format), transcribe it using Whisper, summarize it with GPT-4, and extract both high-level and detailed tasks to display in a user-friendly interface.

Key Requirements:
- Input: MP3 audio files
- Transcription: Use OpenAI's Whisper
- Summarization: Use OpenAI's GPT-4
- Task Extraction: Provide both high-level and detailed tasks
- Output: Summary and To-Do list
- Development Framework: React Native
- Backend: Python and OpenAI API integration

Ideal Skills and Experience:
- Proficiency in mobile app development, particularly with React Native
- Strong experience with Python and OpenAI API
- Familiarity with Whisper and GPT-4
- UI/UX design skills for a simple, intuitive mobile interface
- Previous experience in task management or productivity apps is a plus

Please provide a portfolio showcasing relevant work. Looking forward to your proposals!
