Multimedia Chat App Development

I need a chat application that handles real-time text messaging, instant voice messages, and seamless file sharing in one cohesive interface. All three features must work smoothly together, with quick delivery, playback, and transfer times even on spotty connections.

I have not locked the project to a specific platform, so please outline whether you think a mobile-first, web, or hybrid approach will serve these requirements best. Whichever route you recommend, the final hand-off should include:

• Fully functional chat module compiled and ready to run
• Well-commented source code
• Brief setup guide and API documentation so I can plug it into the rest of my stack without hunting for answers

Security, efficient storage, and clean UI/UX are important to me, but I’m happy to follow your expertise on framework choices—React Native, Flutter, Node.js, or any stack you feel suits the job. Let me know your proposed tech, timeline, and any questions you need clarified so we can get started right away.
