What I do
Data science and analytics
Panel EDA, statistical evaluation, and ranked metrics over large public datasets — 167k-row weather panels, EPA county emissions, and Databricks SQL pipelines feeding published Lakeview dashboards.
ML training and evaluation
Credit default modeling with leakage hygiene and holdout evaluation, day-ahead forecasting on panel data, and baselines reported when they fail rather than quietly dropped.
AI systems in production
LLM features that ship behind guardrails: retrieval that cites its sources and refuses when evidence is missing, and a Gemini owner copilot with NeMo guardrails running in Iter AI Parking.
