GSA Capital - DSG (Data Services Group)
The team is responsible for the design, implementation, and maintenance of all data systems driving trading models. This includes decisions about data storage, processing and delivery. There is a heavy emphasis on robustness.
During my time at GSA, I developed multiple new systems which are heavily relied upon during trading. Frequently, I had to debug and fix production-critical systems in severe time constraints. Common tasks include - system / API design, implementation, and performance optimization. Database design and optimization (both via query tuning and more complex schema/index alteration).
Technologies used: Java, Python, SQL, Scala
