Challenge
Before

Prediction tallying, delivery, and P&L management relied on manual work; processing vast race data each race day, meeting strict delivery cutoffs, and tracking user P&L had become a heavy operational burden.

  • We don't want to tally vast race data by hand every time
    300+ races nationwide per race day
  • We want to deliver predictions reliably, in time for the cutoff
    Strict delivery timing per cutoff
  • We want to accurately track and visualize users' betting P&L
    Manual tallying of hit and payout rates is hard
  • We want to handle broadcasts stably even at peak times
    Weekend peaks, many simultaneous deliveries
Solution
After

From race collection to prediction generation, automated delivery just before the cutoff, and betting-P&L visualization — all on one platform. Unmanned operation for operators, instant Telegram receipt and P&L management for users, and stable processing via queue and scheduler for dev & ops — optimizing all three experiences at once.
