A highly skilled and self-motivated Software Systems Architect with strong technical skills and over twenty years of hands-on experience in software engineering.Strong background in computer systems, software engineering, performance engineering, financial technology. Leading a holistic approach for computer systems engineering, taking into consideration hardware, operating-systems, application programming, and operations.Working in the financial services industry, leading projects from initiation to deployment, and working closely with the IT and operations teams to support the system overall.Currently employed by Virtu-Financial (acquired ITG in 2019). Software design and implementation of electronic trading systems, particularly connectivity-hubs on Unix systems (Linux and Solaris) written in several programming languages, mainly C/C++. A key contributor to a broad range of projects, re-architecting and improving the connectivity-hub. Significant contributions -a. Developed a proprietary in-memory database eliminating the use of a general purpose database within the order-flow, increasing throughput (by 1000x), reducing the code complexity, and achieving competitive low latencies.b. Developed a proprietary real time transaction data publishing system to feed data to internal and external client applications, eliminating the use of the database and making the data-set flexible and easily modifiable.c. Re-architected the connectivity-hub's messaging and data such that it can operate at the same time on different operating systems (Oracle Solaris, Linux) on machines that are powered by different types of CPUs (Sparc, X86), allowing for gradual migration and reduction of the data-center footprint while capacities continued to grow.d. As requests for ultra low latencies increased, developed tools to accurately measure latencies, re-designed, optimized and re-wrote parts of the code, performed tuning of the hardware and operating system to achieve the expected low latencies.PhD (Geodesy, Mapping and Geo Information Engineering) from Technion - Israel Institute of Technology.Areas of expertise:+ Software systems architecture.+ Performance engineering, speed optimizations, ultra-low-latency and high-throughput in electronic trading systems.+ UNIX systems - administration, hardware tunings, and programming.
