Experience
- SmartDisposition for Optoro
This was an API service that drove critical, real-time business decisions. It comprised a directed dependency graph of machine-learning models, internal and external data sources, and expert systems. SmartDisposition executed as many concurrent paths through the graph as possible in order to deliver the best available results on a time-sensitive basis.
I reimplemented the entire application using the Ruby concurrency library and designed a custom domain-specific language for configuring the dependency graph that enabled loose coupling between the graph nodes.
Because the parts of the system all varied in their degree of CPU usage, I/O usage, and reliability, this enabled us to have a robust, performant system that maximized throughput, minimized latency, and could handle failures gracefully.
