iOS & Android mobile application using AI to transform audio recordings into transcriptions, summaries, key points, and action lists.

Designed, developed, and published in 3 days as part of a personal challenge:

Main Features:

Project completed entirely alone, from market and existing solution analysis to development, deployment, and store publication.

I was in charge of the mobile part of an AI-powered call and voice message transcription application developed in Flutter, which I designed entirely from scratch, following Clean Architecture principles and integrating a full range of advanced features, enhanced by artificial intelligence.

This application allows transcription of calls and voice messages using AI, management of a call list, and making calls via an integrated dialer.

It also synchronizes contacts, organizes voice recordings in a file and folder system, and allows them to be played back and transcribed.

Registration and login are done via a phone number, with SMS code verification, in a smooth and secure process. The application also has a waiting list system, which directs users according to their country or service availability, as well as a complete referral and invitation system.

On the DevOps side, I implemented a continuous deployment system with GitHub and Fastlane to ensure fast and reliable updates, as well as an error management system via Sentry for precise monitoring of production incidents.

I also set up a server managing push notifications, based on Firebase Cloud Messaging, as well as a custom logging system and API documentation generated via Swagger, to centralize and structure communication between services.

A mission that illustrates my ability to design, develop, and maintain a complete mobile application, from A to Z. From architecture to user experience, scalability, and DevOps tools, I am an expert Flutter developer capable of delivering robust, modern, and production-ready solutions.

I participated in the transition to a modular architecture inspired by Clean Architecture, while developing major new features: integration of a clustering system on Google Maps, implementation of a VoIP solution, management of push notifications, addition of an instant chat, integration of Google Analytics, as well as various key features: news feed, stories, favorites system, user relationship management, creation and management of real estate listings, and distinct profiles (professional and individual).
