Android SaaS App Developer for Call Recording, Transcription, Summarization, Emotion Analysis & Reminder System (Kotlin/Next.js) Description: We are looking for a developer to build a comprehensive Android-based SaaS application that will be hosted on our VPS and eventually launched on the Play Store. This project will be carried out in multiple phases under a Non-Disclosure Agreement (NDA). Phase 1: Call Recording & History: Develop an Android app using Kotlin to record calls and manage call histories. Transcription & Summarization: Implement an in-house AI system (no third-party tools) to transcribe call audio and then summarize key points from the transcriptions. Emotion Analysis: Use your own AI model to analyze customer emotions from the call content (e.g., detect if they are frustrated, interested, etc.). Lead Management & Reminders: Include lead management features and a calendar-style reminder system for follow-ups. Phase 2: Further enhancements and additional features as needed. Additional Requirements: This is a continuous project with multiple phases of development. The entire project will be covered under a strict NDA. The final application should be Play Store-ready. Please share relevant experience and note that all AI functionalities must be developed in-house without third-party services. We look forward to collaborating in detail!
