Bey-Ru Hsu

I’m a Software Developer focused on building scalable, data-driven systems that improve performance and reliability. I’ve proven success developing trading platforms and modernizing legacy infrastructure, with a strong emphasis on system optimization and automation.

At Morgan Stanley, I designed and implemented a Scala-based market model that increased trading efficiency by 37% and reduced daily operational costs by over $25M. I also built a client-facing app with Scala and Kafka Streams to process and respond to real-time data within seconds, improving accuracy and user experience.

I modernized critical messaging workflows using Java to enable seamless, real-time processing of trading data across departments. I replaced legacy systems with modern technologies, delivering a 38% performance boost and 47% fewer service outages.

I’m passionate about using technology to solve real-world problems, and I enjoy building end-to-end solutions—from data visualization and processing with Angular and Java (reducing response time by 78%) to proactive monitoring and QA automation that improve operational responsiveness and reliability. Earlier, at UniOhm Corp, I redesigned the company website using TypeScript, Angular, and HTML/CSS, driving a 30% visitor traffic increase in two months.
