Rockstar🎓
Top SchoolJerry Shea is a seasoned low-latency systems expert and technology leader with nine years of recent experience driving high-performance trading solutions across APAC as MD APAC at Chronicle Software. He combines hands-on Java performance engineering—contributing to notable OpenHFT projects like Chronicle-Core, Chronicle-Wire and Java-Thread-Affinity—with regional product ownership of billion-event, mission-critical FIX and eFX platforms. Jerry has a strong track record building microsecond-latency market-making, pricing and order management systems, and has led rapid, high-impact transformations such as launching an institutional eFX stack in seven months. Comfortable both as a coder and a board-level advisor, he improves reliability, uptime and SDLC practices while managing vendor and stakeholder relationships. Unusually, he pairs deep protocol-level expertise in FIX with practical kernel/OS-level fixes (thread affinity, signal handling) that squeeze extra determinism from production JVMs.
