Technology at GSA
In this presentation, we will provide an overview of GSA and what a systematic quantitative fund is. We will outline the role of our Technology teams, including the divisions, technology stacks and how it supports researchers in the development and deployment of trading strategies. Finally, one of our software developers will share a recent project that involved compressing exchange trade and order data into a binary format, reducing the replay time by approximately ten-fold, and enabling rapid generation of intraday equity trading signals.

Junhui Yang joined GSA in 2023 as a software developer supporting the firm’s founder. He works on building and maintaining data pipelines, back testing frameworks, monitoring systems and other critical tools essential to the success of a quantitative fund. Prior to GSA, he read Mathematics and Computer Science at Merton College, University of Oxford and spent a brief period at Meta. Outside of work, he enjoys playing the violin and piano, and is a tea enthusiast.
