Mar 2025 – Present
System Engineer, Lead
ICONS (formerly Institute for Software Integrated Systems), Vanderbilt University, Nashville, TN
- Created and lead Betty's Math, a SvelteKit/TypeScript math assessment and AI-tutoring platform embedded in the OECD's PILA and deployed in a randomized controlled trial across hundreds of schools in France, Germany, the Slovak Republic and Latvia.
- Integrated an LLM tutor into the student experience, with context built from the problem, the student's current solution, a learner model and progress statistics, plus persistent chat history and prompt logging for evaluation.
- Built LLM pipelines (Claude, GPT) that translate problems, concepts and misconceptions for a four-country deployment and generate knowledge graphs used to assign students to concepts.
- Built the platform's research layer (RCT sequencing, xAPI event logging and a real-time teacher dashboard), working directly with the OECD team on wording, translations and dashboard design.
- Lead SyncFlow, an open-source Rust/Next.js/WebRTC platform that sustains 200 concurrent streams at about 200 ms latency and has archived 400+ hours (more than 10 TB) of classroom data for 1,000+ researchers and students.
- Deployed SyncFlow in classroom studies across Indiana, Tennessee and North Carolina for the NSF AI Institute for Engaged Learning, on Amazon ECS and on-premises, and integrated the C2STEM, SPICE, Crystal Island and EcoJourneys learning environments.
- Building real-time AI feedback for classrooms: speech recognition (NVIDIA Riva, AWS Transcribe), computer vision on edge and cloud, and on-device LLM summarization of live classroom transcripts on NVIDIA Jetson.
