      • RTA API
        1. Real-time rules for advertising RTA API, building a complete user rule system.
        2. Handling requests from the platform with a peak QPS of over 60,000, deploying over 300 pods.
      • Ad Attribution
        1. Users click on ads, download the app (acquisition) or open the app (reactivation).
        2. The ad platform sends requests to the server, caches the attribution factors, and sets the attribution period.
        3. Adding a delayed queue to perform attribution again (to prevent attribution failure due to reactivation timing issues).
        4. Successful attribution will result in targeted content push on the app’s homepage (pushing content based on the ad copy the user clicked).
      • Alliance Ad System
        1. Adopting the laravel + laravel-s architecture.
        2. Supporting ad requests from over 2 million daily active users.
        3. Handling billions of ad data requests.
      • A/B Testing
        1. Client-side and server-side testing (for quickly testing recommendation algorithms).
        2. The statistics platform displays test metrics, mainly including play count, duration, and retention rate.
        3. Allowing multiple test groups to run in parallel and creating mutually exclusive groups.
        4. User filtering based on attributes such as new/old users, devices, and channels.
        5. Intelligent traffic allocation, with better-performing groups receiving more traffic.
        6. After the test is completed, selecting the test plan, and the server directly returns the plan result, allowing the client to determine the plan without a new release.
