Kalise — Live Streaming & Social App

The problem

Kalise needed to be three real-time products in one app: live streaming where hosts broadcast to audiences, random one-to-one audio and video calls that connect strangers instantly, and a gifting economy where viewers buy virtual gifts and send them to hosts mid-stream. Each of those is hard on its own; together they demand an app where video, payments, and state all stay in sync while users hop between rooms.

What I built

A cross-platform Flutter app with Agora doing the heavy real-time lifting.

• Live streaming rooms. Hosts go live through Agora's RTC channels; viewers join with near-zero setup. Room state — who's live, viewer counts, gift events — synchronizes across every client in real time.
• Random call matching. A matching flow pairs users for one-to-one audio or video calls, handling the messy real-world cases: one side disconnecting mid-ring, permissions denied, networks dropping mid-call.
• Gifting with real money. Viewers top up coins through Razorpay, then spend them on animated gifts during streams. Payments are verified server-side — a gift only renders after the money is real — and every transaction is recorded for host payouts.
• The unglamorous 40%. Auth, profiles, blocking and reporting, push notifications for "your favorite host is live," and the moderation hooks a social app needs on day one in the stores.

Outcome

Kalise shipped to production as a complete social platform: streaming, matching, and monetization in one Flutter codebase for both Android and iOS. The gifting economy gives hosts a reason to stream and the app a business model from launch.
