I need all customer conversations to live inside our product, with chat as the only channel. Please plan, build, and hand over a full in-app chat solution that lets visitors or logged-in users message our support team in real time. Scope • Add a clean, responsive chat widget to both web and mobile views of our app. • Provide real-time two-way messaging with typing indicators and basic read receipts. • Include a lightweight agent dashboard so my team can pick up, tag, and archive threads easily. • Use a reliable framework—Firebase, Socket.io, Twilio, or a comparable SDK—so maintenance stays simple. • Deliver thoroughly commented source code, plus a short setup & hand-over guide. If you have similar builds in your portfolio, that will help me gauge fit quickly.
