Enhance Chat App: Voice & Video

I have an existing web-based chat application that is stable in text messaging, but I now need it to feel complete. The two core features still missing are voice messages and real-time video calls, and I want both implemented end-to-end—from intuitive UI controls to the backend signaling and media handling. Alongside those media features, I’d like to polish the user experience. Specifically, the notification system has to be more engaging: sound alerts for new activity, push notifications that work reliably in modern browsers and on mobile PWA installs, and optional email notifications that respect user preferences. Presence is equally important, so please add live user status indicators (online, away, typing, etc.) that sync accurately across tabs and devices. Key deliverables • Voice messaging: record, send, play, and store audio clips with adaptive bitrate and clear waveform preview. • Video calling: one-to-one WebRTC call flow with mute, camera toggle, and call timer, all wrapped in a responsive layout. • Notification overhaul: configurable sound alerts, service-worker push notifications, and fallback email notices. • Status indicators: real-time online/away/typing badges tied to existing auth and socket infrastructure. • Clean, well-documented code plus a brief setup guide so I can deploy the updates to staging and production. The project is already running on a Node.js + Express backend with a React front end and [login to view URL] for live messaging; feel free to suggest proven libraries (e.g., WebRTC APIs, RecordRTC, or Twilio TURN servers) if they accelerate quality. I value maintainability, so keep the architecture consistent with what’s in place and write concise comments where logic gets complex. Once everything is integrated and unit-tested, we’ll do a quick review on a feature branch before merging. If this milestone goes smoothly, I have more roadmap items we can tackle next.
