Top SchoolJacob Dufault is a core developer with 12 years of experience building high-performance systems at firms including Hudson River Trading and Google, where he worked on Spanner, Compute Engine performance, and Chrome OS. He brings deep back-end expertise and a pragmatic focus on performance and correctness, having optimized serializers and removed allocations to speed float serialization in the widely used fullserializer project. Jacob authors cquery and maintains fullserializer, a robust JSON serialization framework popular in Unity contexts, demonstrating sustained open-source stewardship alongside his corporate work. His background spans low-level performance tuning, distributed systems, and practical tooling, informed by a Computer Science degree from Florida Institute of Technology. Colleagues know him for quietly fixing tricky serialization bugs and making incremental refactors that yield measurable runtime improvements.
