About
I build AI Agents for AX — turning inefficient and repetitive work into AI-assisted workflows that improve productivity for organizations and individuals. My work centers on designing and developing tools, workflows, skills, and memory for LLM-based agents.
I've collaborated with Hyundai Motor Group, i-SENS, and SNC Lab on R&D projects, building and deploying these agents inside their organizations — from generating UI that follows a company's design system, to analyzing manufacturing QC data, to auditing web accessibility and writing reports.
