I build AI systems that people can trust with real decisions — and I've learned that trust comes from evidence, not from eloquence.
I started my career on factory floors. At Isfahan Steel and later Reef Chemical Industries, I used statistics and machine learning to predict equipment failures. It taught me something I still rely on: a model only matters when the people running the operation trust it enough to act on it.
That question — how do you make a system trustworthy when someone may be actively trying to break it? — took me to the University of Texas at San Antonio. My Ph.D. research used game theory to model attackers and defenders of cyber-physical manufacturing systems and to quantify where security investment pays off. I taught engineering students along the way.
Since 2020 I have been at H-E-B, where I lead AI and data-science work as a hands-on technical lead: demand forecasting that cut forecast error roughly in half, markdown and shelf-space optimization, and, more recently, LangGraph agentic workflows on regulated data. I work directly with executives on what to build, set the evaluation bar for the team, and still write production code.
Outside the day job I build a public portfolio of AI applications for regulated decisions — credit, clinical, trade surveillance — each with independent verifiers, human review and honestly reported limits. I teach agentic and generative AI programs offered by Johns Hopkins University and UT Austin, and I serve as an AI and technology board advisor to the health-tech startup Syne Life.
Outside work
I live in San Antonio, Texas. When I'm not working you'll usually find me climbing, in the mountains, or at a CrossFit box — pursuits that reward the same patience and respect for risk that good engineering does.
The path
How I got here
-
2009 – 2015
Factory floors
Maintenance analytics at Isfahan Steel, then ML anomaly detection at Reef Chemical Industries that cut downtime by 30% and saved more than $200K a year.
-
2016 – 2019
Ph.D., UT San Antonio
Game-theoretic models of attackers and defenders in cyber-physical manufacturing, while teaching engineering students.
-
2020 – today
H-E-B
Hands-on technical lead for forecasting, optimization and agentic-AI platforms used across the business.
-
2025 – today
Teaching & advisory
Instructor in Johns Hopkins University and UT Austin programs; board advisor to Syne Life.
Beliefs
What I hold myself to
-
Start with the decision, not the model
Every system I build begins with the decision it improves and the person who owns it.
-
Evidence before scale
Evaluation, backtests and baselines come first, so we know it works before we bet on it.
-
Humans own high-stakes calls
AI assembles evidence and drafts; accountable people decide where the stakes demand it.
-
Auditable by default
Every number, claim and citation can be traced back to its source and checked by code.
-
Honest limits
I publish where a system falls short. Knowing the failure modes is what makes it safe to use.
