Reactive Summit 2017

No one likes waiting, especially for loan approvals. So when my team at Capital One needed to upgrade our auto financing loan origination systems for near-real-time decision making at high scale, we brought in Akka, Spark and Cassandra to create a brand new user experience. In my presentation, I'll go over how our team created an easily modifiable and flexible loan approval platform. We'll talk about requirements and decisions which lead us to select Akka, Spark with Cassandra to modernize our existing stack in an efficient way, including: 
- The need for sub-second response times, while meeting all corporate SLAs.
- Handling market-based testing and validation of frequently changing credit policies & pricing plus the integration of credit bureau data and evaluation of credit performance.
- Supporting various analytical models designed to detect fraud as well as segment services and policies for different markets, with both online and offline data analysis for continuous improvements.
- Some lessons we learned along the way in building, deploying and managing these clustered applications while keeping our infrastructure footprint as small as possible.
