Seacliff, California, United States
Summary
🤩
Rockstar🎓
Top SchoolTodd Montgomery is a senior software engineer and systems architect with over two decades of deep experience building high-performance, low-latency messaging systems used across electronic trading and real-time platforms. He designed and shipped pioneering broker-less messaging products as CTO of 29West and later led Ultra Messaging architecture at Informatica, and has held chief-architect roles at Kaazing and other messaging firms. An active open-source maintainer and contributor to Aeron, Agrona, and Simple Binary Encoding—and a contributor to RSocket—he focuses on low-level protocol design, concurrency primitives, and binary codecs that squeeze predictable performance from networks and JVMs. Todd combines academic research (NASA-funded networking work and university lecturing) with hands-on engineering and consultancy through StoneTor and roles at DRW and Adaptive, giving him a rare blend of theory and production-hardened practice. Notably, his contributions often target portability and tooling (Windows/C++ fixes, test improvements, and build portability) that smooth adoption of high-performance libraries across platforms.
