Impact

  • < 100 ms average ticker latency worldwide (dataplane p95).
  • Serves 1.2 M websocket messages‑per‑minute during peak volatility with 99.99 % uptime.
  • AI answers reduce support tickets by 63 % and keep cost per answer at $0.003 via caching.
  • Exchange comparison drives 18 % higher click‑through to partner on‑ramps versus baseline widgets.
  • Serverless footprint lowers infra spend 40 % compared with container prototype.

2. The Challenge

  • Streaming precision — price tiles, charts, and heat‑maps must update every 5 s without page reloads or data jitter.
  • AI at scale — ChatGPT answers thousands of open‑ended queries daily; the prompt pipeline needed guard‑rails and caching to keep unit costs low.
  • Exchange aggregation — pull fees, liquidity, and KYC rules from 15 + exchanges and normalise the data for fair comparisons.
  • Fiat on‑ramp security — integrate third‑party checkout while enforcing KYC/AML and shielding PCI data.
  • Traffic volatility — bull‑run surges can triple concurrent websocket sessions; infra had to autoscale within 60 s with zero cold‑start lag.
