Work

Four systems from EHS and applied AI work at Hexion, plus one independent ontology design on public OSHA data, each written up in full. Every case reads the same way: the problem, what I did, the measurable outcome, and what it means for the people who rely on it.

Plant Blueprint, a Synthetic Digital Twin

Problem
Public chemical-plant statistics are tables; it is hard to see which figure can honestly describe which kind of unit.
What I did
Built an interactive 3D blueprint of a generic plant with a seeded simulation whose incident rates come from committed EPA RMP and OSHA outputs, plus Foundry-style alerts, actions and an audit log.
Status
Live. A synthetic site, not a real facility; no live telemetry, behaviour is a model and every statistic cites its source file.

Designing a Safety Ontology

Problem
A pipeline shows that a few implausible OSHA filings can move the national injury rate; an EHS team needs to act on that per site and per filing.
What I did
Designed a Foundry-style ontology: linked object types, governed analyst actions with an audit log, and functions that reuse the tested pipeline.
Status
Merged and tested on a synthetic fixture; the real-data path has not been run. Not affiliated with Palantir; no employer data.

EHS Insight Hub

Problem
Cases, events, concerns and insights sat in separate lists, and each report could count them differently.
What I did
Modelled them as 12 linked Foundry object types, put every KPI and status rule in one logic module, and built a Gensuite-style widget on top.
Status
Verified on a Foundry branch over 190 cases, 1,221 events, 11,546 concerns and 82 insights; merge proposal in review.

Gensuite Refresh

Problem
Every global site captured safety data through an aging interface, each with its own workaround.
What I did
Led a two-phase refresh of Hexion's enterprise EHS application, from requirements through global rollout.
Outcome
80+ feature enhancements; every global site now captures safety data through the refreshed version.

Micro Market Model

Problem
No shared model for comparing competitive opportunity across dozens of micro markets.
What I did
Built a Python linear-programming engine that scores and ranks those markets from an explicit objective and constraints.
Outcome
Adopted company-wide and awarded the Transformation Award.
Stack

3agent platforms, one grounding layer

Enterprise Agent Layer

Problem
An agent answering freely from live systems can produce a fluent, wrong safety number.
What I did
Built the MCP architecture that grounds NLQ and summarization agents in live systems, with deterministic code for exact calculations.
Outcome
Agents in production on Copilot Studio, Claude Code and Codex, with an audit trail behind every answer.
