Oregon Department of Education Currently engaged Oregon Department of Education Business Intelligence Analyst · Since Dec 8, 2025

Epsilon Labs

Decision-grade statistics, scoped to ship.

I help teams design experiments, build predictive models, and stand up the analytics behind real decisions. Documentation that survives an audit. Tooling your team can keep using.

What I do

Four practice areas.

All services →

Statistical analysis & modeling

Experimental design, hypothesis testing, regression, and Bayesian inference for questions that deserve careful answers.

Predictive modeling & ML

Classification, forecasting, and risk scoring with proper validation. Models built to hold up under audit.

Interactive dashboards

Self-service decision tools your team can poke at without me in the room.

Reproducible reporting

Pipelines that document their assumptions, version cleanly, and produce the same numbers next quarter.

AI-native

Models I work with daily.

Frontier models are not optional anymore. I use them every day — for code, for drafts, for analysis pairing — and I know how to tell when they're confident versus when they're guessing.

ChatGPT

Reasoning, drafting, code review at speed.

Claude

Long-context analysis, careful writing, hard problems.

Gemini

Multimodal exploration, large doc ingestion, fast iteration.

I treat models as collaborators, not oracles. I write the prompts, run the evals, and validate the output against ground truth before anything ships.

How I work

Four things you can expect.

Decision-focused

Every analysis answers what should we do next — not just what happened.

Explainable

Validated with proper holdout and cross-validation. I default to interpretable methods so stakeholders can trust the answer.

Reproducible

Documented assumptions and reruns that produce the same numbers next quarter — or tell you precisely why they can't.

Production-minded

I ship lightweight tools, instrument usage, and iterate so the work compounds instead of fading.

Hire me

Have a question worth answering carefully?

Send the question, the data you have, and when you need the answer. I'll reply within two business days with next steps — or a referral if I'm not the right fit.

Backed by graduate training in Statistics (M.S., Oregon State) and Data Science (M.S., Willamette) — the foundations live underneath every model and every report.
