Quantitative Engineer - Low Latency Trading

June 2010 – December 2010 (7 months)
SAC Global Investors is the European subsidiary of the US based SAC Capital hedge fund. I joined the London offices to run high frequency trade support.
• Took ownership of all the European high frequency trading platforms; quickly established close working relationship with brokers and network providers enabling fast production issue identification and resolution.
• Worked with the portfolio managers to migrate their trading platforms to the latest iteration of the company's proprietary 'Ohms' platform within pre-defined time frames.
• Systematically identified areas for improvement, e.g. lack of common toolset for the support team to use; framework upon which to build a toolset; lack of audit trail on config file changes. Designed, developed and seamlessly implemented these tools and changes into the existing production environment.
• Managed fast, efficient, error-free system migration to lower-latency broker-execution platforms, resulting in at least 2-3ms latency reductions in round-trip-time.
• Designed, developed and implemented high-speed Java XML market data feed handler for EBS Ai, allowing the data to integrate into one team's high frequency FX trading platform.

• Regularly identified areas for improvement and developed the most appropriate solution. e.g. built standard framework for monitoring and alerting on time-series data; built a Python jabber bot for the company's Instant Message network for real-time alert communication of system issues.
• Developed a console based application to provide up to the second insight onto the FX trading platforms.
• Worked with development, research and network teams to test and keep abreast of new, upcoming technologies which may improve the company's edge.
