Andrew Simonson

Data scientist at Ecolab and a graduate student at RIT. I build end-to-end decision machines: from data pipelines that process scale, to epistemic models which understand, to user interfaces that convey.

Today

At work
Primary model developer on RushReady at Ecolab: explainable anomaly detection, plus brand-configurable recommendations for quick-service restaurants, all running on a near-real-time Delta Live Tables platform.
At school
M.S. in Data Science at Rochester Institute of Technology, focused on probability theory, statistical learning, and Bayesian methods. Capstone in fall 2026.
At home
Running a two-GPU homelab that serves Mixture-of-Experts models to coding agents over local endpoints, and using the same rig to fine-tune small models.

Selected work

Everything

  1. RushReady at EcolabPrimary model developer, inception to multimillion-dollar product. +20% speed of service.
  2. AI Homelab and Self-Hosted Web ToolingMixture-of-Experts inference beyond rated VRAM, plus fine-tuning, on hardware I run myself.
  3. Human vs AI Code Smell Study85K+ code definitions: AI code carries 3–4x more structural debt.
  4. Reactive Chemistry Analysis at DowReplaced 4 legacy tools; became the interdepartmental standard, saving ~0.65 FTE a year.
  5. Stereo Particle-Track Classification in a Cloud ChamberM.S. capstone, proposal approved: 3D particle-track reconstruction with Bayesian classification.

I wasn't really expecting anyone to read this far. If you're looking for shared resources you've taken a wrong turn.

From here, we'll rekindle the future.
