Modeling & Analytics Software

HYSYSAspen PlusPromaxSuperChemProTreatSeeq

Process Simulation

HYSYS, Aspen Plus, Promax, and ProTreat models that capture real plant behavior — the structured physical layer any industrial AI must respect.

Historian Data Fluency

Seeq-based analysis across years of operating data: the same time-series foundations ML pipelines consume for anomaly detection and optimization.

Root-Cause Rigor

Incident review, RCA, and PHA discipline — translating messy field reality into the clean, labeled outcomes models need to be trustworthy.

AI-Ready Mindset

Ready to pair 14 years of engineering judgment with AI/ML tooling to move from reactive troubleshooting to predictive optimization.

Areas of Expertise

Deep, plant-floor specialization

A dozen disciplines honed across ethylene, olefin, and natural gas processing — the domain knowledge that makes optimization meaningful.

Chevron Phillips Chemical Company

Process Engineer

Port Arthur, TX

May 2020 – July 2026
  • Served as process engineer for one of North America's larger and lower-cost ethylene manufacturing facilities, providing technical leadership, troubleshooting, process safety support, and capital project development.
  • Frequently led the Process Engineering team during the Lead Process Engineer's absence, coordinating priorities and supporting operational decision-making.
  • Completed Cracked Gas, Propylene Refrigeration, and Ethylene Refrigeration Compressor mechanical limit studies — the basis for the plant debottlenecking study.
  • Led the process dryer dump-and-reload effort for the ethylene unit, coordinating operations, maintenance, and engineering to safely restore equipment performance.
  • Worked with vendors and SMEs to complete the FEED study and design of a marine vapor combustion unit (MVCU) system.
  • Played a significant engineering role in the 2025 1544 Turnaround — troubleshooting, planning, startup support, and risk reduction; managed 4th-stage suction drum work to address a known unit limit and increase throughput post-startup.
  • Led a study reducing pyrolysis tar accumulation and emulsion formation in the quench water system, improving operability and reliability.
  • Served as the site's PRD/PSV Subject Matter Expert, supporting relief system evaluations, overpressure protection studies, and PSM compliance.
  • Currently leading the Furnace backflow project to prevent hydrocarbon backflow from the Quench Tower.

Honeywell UOP

Senior Process Engineer

Tulsa, OK

Oct 2017 – May 2020
  • Modeled PFDs, heat and material balances, and P&IDs at facility level using HYSYS, Promax, and ProTreat.
  • Developed PFD for a 200 MMSCFD gas subcooled (GSP) and recycle vapor split (RSV) process.
  • Created a design guideline for Air-Cooled Heat Exchangers (ACHE) adopted by the process engineering department.
  • Designed the compressor system for recycling tail gas and trained new process engineers on workflow.
  • Ensured sound engineering design of compressors, tower internals, brazed aluminum exchangers, and pumps with OEMs.

Baker Hughes

Production Engineer

Sand Springs, OK

July 2014 – Oct 2017
  • Drove savings of 20% profit per year by reducing batch time on resin products while maintaining quality.
  • Completed a solvent recovery unit (SRU) improvement project delivering 15% savings per year.
  • Identified and resolved complex scrubbing solution level loss in a benzene scrubber sump.
  • Led various process hazard analyses and PSM efforts; implemented PHA and root cause analysis action items.

Exterran

Process Engineer

Broken Arrow, OK

May 2012 – July 2014
  • Created equipment data sheets for heat exchangers, vessels, demethanizer, filters, pumps, towers, and turboexpanders on a gas subcooled process plant.
  • Championed cause-and-effect matrix, hot oil system study, flare study, instrument air calculation, and mol sieve adsorption/desorption study.
  • Utilized process simulation software to design and optimize natural gas processing plants — gas treating, dehydration, refrigeration, distillation, cryogenics, and rotating equipment.
