Challenge
Before

A goal to design from scratch a live-streaming experience satisfying 'instant delivery,' 'two-way interaction,' and 'monetization' all at once. Off-the-shelf video SDKs imposed several-to-10-second latency, gift-effect lag, and operational load that held back business growth.

  • Need to minimize live latency
    Off-the-shelf SDKs take 5–10s, and the energy cools
  • Need to deliver gift effects without delay
    Super chats stutter from animation lag
  • Need to respond instantly to high volumes of user reports
    Delays in detecting inappropriate streams damage the brand
  • Need to automate revenue sharing to streamers
    Excel-based operations can't scale to thousands
Solution
After

Amela designed and built the end-to-end system with iOS Native + WebRTC + RxSwift. Facial landmark detection via Dlib integrated through an Obj-C++ bridge, plus an in-house Low-Latency Viewer module achieving sub-second latency. A Vue.js admin panel centrally manages streaming, users, and revenue.
