About

Who I am

I'm a U.S. Army Warrant Officer and a Field Artillery targeting technician — the technical specialist a command relies on to turn a commander's intent into precise, accountable effects under time pressure and real uncertainty. Across joint and multinational operations, my career has been one long exercise in the same discipline: translating ambiguous, high-consequence problems into structured plans, defensible decisions, and executable actions where being wrong has a cost. It left me with a durable obsession — how do you make complex, consequential decisions legible, verifiable, and worth trusting?

I don't just operate inside those systems; I work to improve them. My professional writing on closing the gap in artillery effects expertise earned the Army's CW5 John A. Robinson Eagle Writing Award, arguing for deep technical understanding over blind reliance on black-box tools — the same conviction that now drives the software I build. Most of that energy currently goes into WITAN, a personal AI system assembled from many small, local, observable models rather than one large opaque one, built to turn scattered intent into verifiable action.

That building runs alongside deliberate academic movement toward AI systems engineering. I hold a master's in management with a focus on IT project management, and I'm pursuing an M.S. in Systems Engineering at Johns Hopkins University's Whiting School of Engineering, concentrating on artificial intelligence and human–team systems — the formal grounding beneath the systems I'm already building by hand.

In parallel I coach and advise early-stage founders and high-performing professionals, helping them navigate uncertainty and build resilient operating systems as they scale. Across all of it — targeting, engineering, coaching, code — the throughline holds: turn ambiguity into structured, verifiable action, and build systems people can actually trust.

Beyond Destruction: Bridging the Gap in Artillery Effects Expertise

★ CW5 John A. Robinson Eagle Writing Award

In Large-Scale Combat Operations, the U.S. Army faces a persistent tactical gap in artillery employment driven not by a lack of systems, but by an insufficient understanding of surface-to-surface munitions effects among practitioners. Although doctrine such as FM 3-60 emphasizes effects-based targeting, and tools like Joint Weaponeering Software and the Advanced Field Artillery Tactical Data System provide statistically rigorous solutions, their effectiveness at the tactical level is constrained by operator understanding, data quality, and time. Reliance on simplified adjudication tables and reductive destroy–neutralize–suppress frameworks distorts expectations and erodes confidence in fires, despite modern artillery demonstrating unprecedented precision and effectiveness in contemporary conflicts. To close this gap, the paper proposes an advanced munitions effects course developed beyond software operation — building deep, technical expertise in blast, fragmentation, fuzing, aimpoint manipulation, and nonlethal effects, modeled on established joint and sister-service programs. Centered on 131A Field Artillery Targeting Technicians as the Army's effects subject-matter experts, this course would enable more accurate, flexible, and scientifically grounded targeting decisions, ensuring artillery can fully realize its potential in LSCO under both permissive and constrained conditions.

Projects

The problems that pull me in all have the same shape: taking ambiguous human intent and turning it into action a machine can carry out — and a person can verify. How people decide under pressure, how AI earns trust instead of demanding it, and how small, inspectable pieces compose into something that rivals a black box.

Tech-wise that means local-first AI, multi-agent orchestration, the harness engineering that makes probabilistic software dependable, and observability deep enough to prove — or falsify — a design. I build the whole stack: the models, the contracts between them, the fleet they run on, and the surfaces a human actually uses.

Soldiers don't wait for AI. They build it.

Featured for my team's second-place finish at the U.S. Army's Vantage Edge 2 AI competition — a five-day sprint where 300+ participants across 42 teams shipped production-ready AI solutions to real operational problems. Out of Joint Base Lewis-McChord, we built an AI workflow that consolidated land, ammunition, training, and readiness systems into a single forecasting and planning dashboard, addressing a challenge shared across Army divisions.
