Making a cross-platform encrypted messaging app requires not just any developer, but rather an experienced one that brings a wealth of expertise in mobile app development for iOS and Android - like myself. With 10+ years in Full-Stack development, I have successfully completed over 100 projects, many like yours involving complex functionalities and security protocols. Moreover, your project requires advanced knowledge of encryption technologies - another strength I possess. I have a deep understanding of how important security is in messaging apps. My focus will always be to implement strong end-to-end encryption for messages and calls, ensuring that user privacy is revered at all levels. Group chat functionality and multimedia sharing are two features that I am extremely well-versed with as they are consistently used in my previous projects. To reassure you about my approach to security and privacy, I will ensure to implement the latest encryption protocols available. All code will undergo rigorous testing to identify and rectify any potential vulnerabilities. Finally, my dedication to quality means I will not only deliver a product on time but also ensure it's scalable, stable, and secure for long-term use. Let's connect our ideas and make a secure messaging app that will keep user conversations confidential.

End-to-end encryption is the core. Off-the-shelf libraries don’t cut it—you have to handle key exchange, device verification, and secure media transport directly or you introduce real risk. I built a secure communications module last year for an enterprise app with E2E text, calls, group chat, and file sharing. That stack was Flutter for both iOS and Android, signaling over WebRTC for calls, and message payloads encrypted using the Signal protocol. For this, I’d use Flutter (one codebase), Node.js backend, PostgreSQL, and implement double ratchet encryption for all messages and attachments. Group management, media uploads, device trust, and push notifications all need close handling. Are you supplying your own authentication system or should I build that layer as well? Pradeep
