†Equal-contribution undergraduate authors.

xAI Summer 2025, remote. Contributed to training of grok-code-fast-1. Integrated LLMs into autonomous agent frameworks spanning 20 tools across thousands of production workflows and codebases; diagnosed and resolved 50+ agentic failures, improving tool-execution rates by >15%, reducing fatal tool-usage errors by >40%, and reducing API usage by >20%. Contributed to safety systems, reducing hallucination rates by >50% in controlled agent-behavior tests.
NeuroAI Present. neuroai.health. Early-stage venture of academics and clinicians integrating deep learning, reinforcement learning, and generative AI into clinical and research workflows; leading research-engineering across model development, deployment infrastructure, and system design.
Shu Laboratory, Brown Department of Neurology — Undergraduate Researcher and Technical Lead. October 2023 – Present. Technical lead on NeuroPose; co-lead developer on the ICD-10-CM embedding model.
Independent Research Contracting — Anthropic, Mistral, OpenAI. 2025 – Present Expert reasoning contributions in code and mathematics for agentic workflows, agentic task design and evaluation, AI safety, and red-teaming.
