Rockstar🎓
Top SchoolPaul Calabrese is an experienced engineering partner with 20 years in software and a long professional arc stretching back to engineering roles at McDonnell Douglas. Based in Ballwin, Missouri, he now helps lead Object Computing, Inc., blending hands-on systems work with strategic technical leadership. His open-source contributions include low-level network performance improvements to the high-profile EOSIO blockchain, where he implemented "greedy reads" and message buffer refactors to optimize network I/O. That work reflects a deep practical understanding of networking, data streams, and performance tuning—skills he applies to complex enterprise systems. A University of Dayton alumnus, Paul brings a pragmatic, systems-oriented perspective honed over decades in aerospace and software.
