Robinhood is democratizing the financial systems by offering commission-free investing and trading with the use of your phone or desktop. As exciting as that sounds to the outside world, internally, the team at Robinhood must understand the different risk vectors and build engineering solutions to mitigate these risks. In this talk, Allison will talk about how they build a real-time risk monitoring system with InfluxDB and Faust, an open-source Python stream processing library. She will review the architecture behind the system which will involve both the time series anomaly detection part (InfluxDB) and the real-time stream processing part (Faust/Kafka).
