Top SchoolSiyou Pei is a founding product engineer and PhD-trained software engineer with 8 years of experience building high-performance distributed XR systems and AI/ML applications. They have a track record of turning research into production—contributions adopted by the Meta SDK and a deployed system at JPMorgan Chase—and have delivered up to 6x speedups and sub-50ms latencies for real-time collaboration. A patent holder with seven peer-reviewed publications and leadership across seven projects, Siyou blends deep systems engineering (Python, C#, C/C++, Unity) with practical product delivery and mentorship of junior researchers. Notably, they achieved 120fps vision-based force estimation on mobile devices with <0.3N error and built reusable frameworks that connect ML backends to robots and XR clients. Now based in New York and open to software engineering roles starting Summer 2025, Siyou is focused on AI-enabled product experiences that meaningfully reduce user friction—most recently automating timesheets for legal teams.
