ABOUT ADDISON JAMES
Staff Machine Learning Engineer focused on high-stakes decisioning in commerce, fraud, and risk. I build and operate production ML systems end to end, from problem framing and evaluation through deployment, monitoring, and iteration.My work sits at the boundary of modeling, experimentation, and production systems. I set experiment direction and launch criteria, turn ambiguous problems into executable technical plans, and help teams deliver through design reviews and hands-on debugging when it matters. I care about reliability, latency constraints, and measurement.Previously at Intel, I built real-time ML decisioning systems that delivered $25M+ in annual savings and automated engineering hours. I also led a 200x performance optimization of a Python ranking pipeline that materially reduced time to resolution, and shipped production computer vision workflows for defect detection.My background spans fraud and risk decisioning, large-scale data and pipelines (Spark), experimentation and tracking (MLflow), feature platform patterns, and model health monitoring, including drift and performance shift.
