The Sports book Platform team owns the backend that powers the Score Bet Sports book. We are the team behind the marketplace: the event, market, and page-composition systems that decide how bets are surfaced, organized, and updated for the user. What we own is everything around markets: how markets are modelled, how pages are composed, and how quickly changes propagate to patrons.

Our stack is primarily Elixir and Phoenix, backed by PostgreSQL, Kafka, and a service mesh of gRPC and GraphQL endpoints running on Kubernetes. We operate at the scale and latency that live sports demand, which means we care deeply about production hygiene: load testing, tracing, structured monitoring, and clear on-call expectations.
