Conceived and developed a proprietary application services framework in C++17, synthesizing over 20 years' experience in financial systems design and development. The platform, designed to serve as the basis for sophisticated transaction systems, enables run-time discovery and loading of modules written in C/C++, Java, JavaScript and Python, and provides these modules with a broad and deep collection of services, including a full messaging suite supporting both publish/subscribe and request/response messaging models, between threads and local or remote processes.

Early member of development team that created Serve, an autonomous sidewalk delivery robot named one of Time magazine’s “Best Inventions of 2019”. • Developed a novel bandwidth-adaptive compression algorithm for lidar data. • Developed a safety framework to override autonomous and manual commands based on sensor data, and proximity detection modules using lidar and sonar data. • Developed device firmware for the Cortex M4 running FreeRTOS, including a UART Driver and a GPS driver including NMEA parsing and hardware clock disciplining. • Designed and implemented a service discovery protocol, server and C++ client APIs.

Collaborated with Electronic Trade Order Management System (ETOMS) team on a greenfield project to create an automated quoting and order routing system for fixed income and FX cash and derivatives. These components formed the core of a new, high-growth line of business.◦ Designed and implemented a test harness for the Quoting Engine to emulate the front-end GUI, providing scripting capability using a custom domain-specific language.◦ Re-engineered the database components for performance, scalability and maintainability.◦ Built a variety of infrastructure components, including an API to interface legacy Bloomberg infrastructure to the new components; a proxy server co-located with the exchange feed; and a heartbeat system to allow the components to monitor each other’s status.

Engaged by Architecture and Development team to design and build solutions for the high-profile merger of Merrill Lynch into Bank of America.◦ Rapidly developed numerous feeds to meet aggressive timelines for risk management and regulatory compliance. ◦ Created a low-latency trade message prioritizer in Java/Spring using XPath, JEval and MQ Series. Improved trade service levels by re-arranging the trade queue according to user-defined rulesets.◦ Developed a system for reconciling risk-transfer deals for liquidity aggregator positions, enabling traders to deal on best available prices while managing risk.◦ Reduced client’s integration costs by creating a plug-in data extraction architecture, enabling support staff to create data extracts without coding.◦ Achieved or exceeded all business goals and timelines for integration of the two businesses, providing a seamless transition to internal and external customers.
