🤩
RockstarHarold Hunt is a seasoned software engineer with over a decade of experience modernizing large-scale financial and enterprise systems, particularly at Thomson Reuters and Bloomberg. He specializes in pragmatic migrations and hybrid architectures—shifting legacy C++/GDI charting to D3.js with C++ calculation backends, consolidating login services into enterprise SSO, and rebuilding deployment/targeting pipelines for Node, .NET, and Java. Known for solving performance and scale problems, he has migrated multi-billion-row databases, replaced core high-throughput databases, and authored a widely taught class on designing high-performance DBs. He combines hands-on systems development (including a custom async web server) with developer advocacy, having documented and promoted platforms to hundreds of engineers. A practical innovator, Harold’s work consistently reduces costs and hiring risk by favoring maintainable, language-appropriate stacks. Based in the New York area, he brings a track record of turning complex legacy challenges into robust, scalable production systems.
