I will build a realtime chat feature with websockets for your android app


About this gig
Need realtime chat that actually works in production not a Firestore prototype that breaks at 50 users?
I just shipped Chatter, a full chat app with the Ktor + MongoDB backend I wrote myself. Watch the demo: https://youtu.be/pO29lKkpbnY
WHAT YOU GET
WebSocket-based realtime messaging instant delivery, no polling
1-to-1 and group chat on the same pipeline
Online / offline / last-seen / typing indicators
Read & unread tracking handled correctly for both "in chat" and "open later" cases
FCM push notifications that fire even when the app is killed
Local persistence with Room chats load offline
Clean Architecture + Jetpack Compose UI
BACKEND?
Basic/Standard: I integrate with yours (Firebase, Supabase, your REST/Socket server)
Premium: I build you a Ktor + MongoDB backend with JWT 2FA, sockets, FCM production-ready

FAQ
Q: Do I need to provide a backend?
A: For Basic/Standard, yes — I integrate with whatever you have. Premium includes a Ktor backend I build for you.
Q: Will it work when the app is closed?
A: Yes. FCM push wakes the app for new messages.
Q: Can you add voice/video calls?
A: Yes — see my "Voice & video calls" gig, or message me for a bundle.
Q: What if I'm not technical?
A: Send me your app idea in plain English. I'll send back a 1-page scope doc before you pay.
